It's a Christmas miracle: Holly (Amy Ryan) is back on 'The Office' tonight! Hopefully she'll be able to work her magic and save the show from the doldrums known as season 7.

It doesn't get much more classic 'Office' than the storyline where she thought Kevin was mentally challenged, so the expectations are high for her return. Just looking at the picture should be enough to excite any 'Office' fan (along with the fact that she's back for at least eight episodes). Plus, with this being Steve Carell's final season, don't you think Michael and Holly deserve to ride off into the sunset together?

One drawback: The episode is an hour. Typically, 'The Office' loses a little bit of magic when it stretches longer then a half-hour. In a season that has had more lows than highs, can it afford many more drawn-out storylines?

Check out the promo below -- it's classic Michael and Holly. Then, head on back to TV Squad tonight to weigh in on our episode recap.
