'Glee' isn't back until Tues., Nov. 1 and we know it'll be a rough few weeks for Gleeks. However to tide you over, you might want to see these previews from the next all-new episode, 'Pot O' Gold.'

In the episode, 'The Glee Project' winner Damian McGinty makes his first appearance as an exchange student, Blaine (Darren Criss) sings Katy Perry again and Mercedes and Santana cover Christina Aguilera's 'Candyman.' Plus, it looks like Quinn is still scheming to get Beth back.

Check out some episode stills, the songs and a preview video below.

It's that wonderful time of the year: 'The Simpsons' is celebrating Halloween.

In the 22nd annual 'Treehouse of Horror,' our favorite Springfield residents spoof '127 Hours,' 'Avatar,' and many more pop culture phenomenons.

Check out Fox's official description and posters for the event below.

['Gossip Girl' - 'Memoirs of an Invisible Dan']

Lonely Boy definitely lived up to his nickname this week; Dan may be on the cusp of literary greatness, but with friends and family feeling stung by their fictional portrayals, our budding Hemingway found himself alone in a room full of people, and his Amazon ranking certainly won't make waffles with him in the morning.

This week's 'Gossip Girl' was firing on all scandalous cylinders, elevating itself above guilty pleasure viewing to recapture some of the sparkle of its glory days. The whole gang got together, which always guarantees fireworks, and there were moments to tease both the loyal Chair and the Dair fans. Serena's selfishness was back with a vengeance, and Ivy got herself a new ally -- or did she?

Join us after the jump for our five favorite moments from this week's episode.

It was '80s night on 'Dancing With the Stars' this week and that meant big hair, big shoulder pads, acid brights, a guest performance by The Bangles and ... Roger Rabbit?

The seemingly unstoppable Ricki Lake didn't look so smooth doing the Roger Rabbit this week, even after some encouragement from surprise guest, filmmaker John Waters, who gave Ricki her big break in 1988's 'Hairspray.'

Unfortunately, Ricki just couldn't find the beat this week, and that definitely hurt her scores. After scoring two 10s last week for her thrilling 'Psycho' tango and being atop the leaderboard for three weeks in a row, Ricki dropped the ball this week, only scoring a 24 and losing her top spot to J.R. Martinez.

NBC's new programming strategy? 'Prime Suspect' on all the time!

The network previously placed 'Prime Suspect' in the Mondays at 10PM timeslot formerly held by 'The Playboy Club,' but now the show will air on Tuesday, Wednesday and in its regular Thursday at 10PM home.

Have no fear, 'Parenthood' and 'Law & Order: SVU' fans, it's just during the week of Oct. 24. According to Vulture, 'Parenthood' and 'SVU' were scheduled to have rerun episodes during that week.

'The Walking Dead' Season 2 premiere ratings are scary good. More than 7 million viewers watched the second season premiere of AMC's zombie hit.

According to AMC, the premiere was the "strongest telecast for any drama in basic cable history." The episode had 4.8 million viewers in the 18-49 demographic, 4.2 million viewers in 25-54 and a total of 7.3 million.

One of the most anticipated new fall shows has quickly become one of the lowest rated. What happened to 'Pan Am'?

After debuting to more than 11 million viewers, 'Pan Am' is shedding viewers week after week. The Sun., Oct. 16 episode was watched by 5.9 million viewers with a low 1.8 in the 18-49 rating. That's quite some ratings turbulence for 'Pan Am.'

So why are viewers abandoning the ABC period drama? Are you still watching? And if not, why not?

Just when we were starting to get a read on the complex political landscape developing on Season Two of 'Boardwalk Empire,' a massive eruption has shifted everything around ... again. With the Commodore, Nucky Thompson's chief nemesis, incapacitated by a stroke, the anti-Nucky conspirators suddenly find themselves without a leader, and panicked by the thought that betraying Atlantic City's treasurer may be the last mistake they'll make on this Earth.

Nucky's stock, meanwhile, is back on the rise, as he continues to find creative ways to quickly re-occupy the power vacuum we saw forming after his arrest. And as both Thompson and Darmody set their sites on extending their bootlegging operation into Philadelphia, a proxy war looms on the horizon.

To keep track of the deals, deception and death, AOL TV is maintaining the 'Boardwalk Empire' gangster index, a guide to who's up and who's down among HBO's organized criminals.

'Saturday Night Live' is bringing in Emma Stone, Jason Segel and Charlie Day for sweeps.

Day, star of 'It's Always Sunny in Philadelphia,' makes his hosting debut on Sat., Nov. 5 with musical guest Maroon 5. This is Maroon 5's third appearance on the show.

On Nov. 12, Stone makes her second appearance as host. Coldplay will make their fourth appearance on the show was 'The Help' star's musical guest.

I like 'The Walking Dead' again. This comes after not liking 'The Walking Dead' at the end of last season (which I harped on way too much over at Vanity Fair last season) after really liking 'The Walking Dead' when it premiered. But, you see, I still feel a bit burned from last season's debacle. What started as a nuanced and (somewhat) realistic approach to an outbreak that left most of the population of Earth as non-sentient monsters, quickly deteriorated into absolute nonsense. Look, say what you will about 'Lost,' but at least its plot point about a mysterious bunker played out over the course of more than an entire season. 'The Walking Dead' decided to pull off its version of The Hatch (no joke, I really feel the Center for Disease Control was a ripoff of The Hatch -- way more on that right here) – from its discovery to its destruction – in two episodes. It's as if the same virus from the plot of 'The Walking Dead' somehow infected the show itself. (And, as we know, that virus claimed some causalities.) Regardless, whatever the problems were at the end of the last season ... I'm, cautiously, giving the second season another chance. And after watching last night's episode ... I'm, cautiously, optimistic.

['The Good Wife' - 'Feeding the Rat']

I'm waiting to be wowed.

Yes, Season 3 is just beginning to set things up, but after such a thrilling Season 2, it's very easy to let impatience take over.

Starting the episode with the crime and having viewers see the accused was innocent was a nice twist. One person "saw" the crime and said the real witness did it? Yeah, OK. Can you get more blatantly obvious? If there's one thing 'The Good Wife' audience has proven time and time again it's that they're smart. To me, this was a sloppy story. It brought the entire episode down.

Season Six of 'Dexter' has already shown it has two intriguing, disturbing and creepy "Big Bads" working for it in Travis and the Professor. They're murdering people in bizarre ritualistic ways and their storyline was the most compelling part of this episode, yet frustratingly, Edward James Olmos and Colin Hanks were only given a few minutes of screen-time. Using an abandoned temple as an evil lair, they orchestrated a grotesque final scene that made the Headless Horseman look quaint, sending a chopped-up, half-murder-victim, half-mannequin riding on two horses through a Miami block party.

Still, at this point it's unclear exactly what specific kind of twisted cult ideology is driving Travis and Professor Gellar's murderous weirdness. It feels like we should know by now, but I guess we're still in the weird ritualistic storytelling phase of this season's plot set-up. It's something about repentance and purity, but that lack of info is starting to walk a dangerous line between suspenseful and feeling like it's overdue. As Travis put it, "I don't believe what you are saying."

So ... what'd you think of 'The Walking Dead' Season 2 premiere? Do you agree with my earlier expletive-laced assessment?

Yeah, you don't even have to answer that. Just wow.

Now that you've seen what everyone's been talking about, here are a few season premiere reactions from the show's new boss Glen Mazzara and executive producers Gale Anne Hurd, Robert Kirkman and Dave Alpert.

Warning: Major Season 2 premiere spoilers ahead!

['Nikita' - 'Partners']

I love it when a plan comes together, and this season of 'Nikita' seems to be laying out its puzzle pieces so confidently that it's a pleasure to watch the bigger picture falling into place with such precision.

As if Owen working for Gogol wasn't enough of a bombshell in 2.02, this week's installment deftly painted Ari Tasarov and his company into a much larger canvas, one involving Kelly, Nikita, Alex and even Zetrov itself.

Perhaps wiser minds than mine predicted that Ari and Sergei Semak were in cahoots, or that Ari was behind Kelly's escape, but few could've foreseen how intimately intertwined the storylines would become, or how satisfying it was to see such big moves being made so early in the season.

Since Nielsen started keeping track of DVR playback, some shows that seemed like they were on death row showed tremendous gains in key ratings demographics.

According to the New York Times, new comedies 'Up All Night' and 'New Girl' had tremendous gains in the 18-49 demographic after Nielsen factored in DVR playback. 'Up All Night' jumped from 2.4 rating to a 3.5 rating. 'New Girl' debuted to a 4.8 rating -- already a great number for a new comedy -- but went up to a 6.7 rating when delayed viewing was factored in. 'Whitney' also went up from a 3.3 rating to a 4.2 rating.
