Castle: The Complete First Season
One of last year''s breakout hits, Castle combined the old-fashioned crime-solvin' of Murder She Wrote with the delicious Nathan Fillion goodness of Firefly. The supporting cast isn't necessarily up to Firefly levels, but Susan Sullivan is great as Castle's mom, and even the dull, professional Stana Katic promises to become more interesting as the show progresses. However, she is currently being outshone by the child actress who plays Castle's daughter.

30 Rock: Season 3
You may have heard of this show -- it's won a lot of Emmys. That's because it's pretty amazingly funny. This season includes several appearances by Jon Hamm and the episode where Salma Hayek wears a Battlestar Galactica T-shirt. Try not to let the backlash ruin it for you.

The Mentalist: The Complete First Season
Psych comparisons aside, Simon Baker is certainly charming, and I have no complaints about Robin Tunney as his boss. But Tim Kang steals the show with his deadpan, and Owain Yeoman oozes goofy charm. And Amanda Righetti... you just keep doing what you're doing. Which is apparently wearing very tight button-down shirts.

Terminator: The Sarah Connor Chronicles - The Complete Second Season
I just used up my allotted word count on that title. I wonder if a shorter title would have helped the ratings...

Ugly Betty: Season 3 Apparently, they're going to make Betty less Ugly next season, which makes this a collector's item! Buy three!

Taxi: The Complete Fourth Season I would buy this, but I already follow Danny DeVito on Twitter, and it's pretty much the same thing.
