Arrested Development is one of the funniest shows ever. People are missing out.
I currently watch Breaking Bad, It's Always Sunny, House, Dexter, and Castle. Of those, I'd say that Breaking Bad is legitimately good and It's Always Sunny is fucking hilarious.
Just watched the season premiers of Dexter and House. House was good, the Dexter one not so much. The new season of Castle kind of jumped the shark with the Game of Thrones reference, not to mention the ridiculous superhero thing...almost as bad as the vampire episode. If the next episode isn't significantly better, I'm gonna have to reevaluate watching the show.
Also, say what you want about cop shows, but...The Wire. I've never actually watched other cop shows, but that one fuckin' rules.
