On the seventh day of Festivus, TV gave to me... Seven shows a-thrivin'.

The 2009-2010 season is a great one to be on TV-- especially for returning dramas and new comedies. If we had 20 days of Christmas, I probably could have filled the list with shows that were either thriving right out of the gate or making a resurgence after being on the air for several years. As it is, we just have seven slots, so here are some noteworthy series that are thriving this year.

Dexter
I've always liked Dexter, but it's never been appointment TV for me. I've generally been content to wait until the season came out on DVD and knock all of the episodes out in a weekend. However, after a creative dip in season 3, I've found myself positively glued to my television every Sunday night that season 4 has aired. John Lithgow absolutely made the season as the creepy Arthur Mitchell. Plus the finale? I know some of you saw the big twist coming at the end, but I certainly did not. Who doesn't like to end a season with their jaw on the floor?
