I just finished watching the entire series of
Arrested Development for about the fourth time - although it was my first time through it again in about four months.
I can't even tell you how amazing it is. The series has its slow points - some of season one is a drag before they hit their stride, I've gotten sick of some of season two - but when it's good, it's better than anything else I've ever seen. And the last two episodes are probably some of the cleverest television ever made. I can't believe they took it off the air...
Seriously, if you've not watched every last episode, do something about it and buy the DVDs or something. You'll thank me1.
1 Actually, what's weird about it is that it probably takes a while to get into the series. For a while the humor will seem weird and you won't get some of the references until you watch them a few times, but I can't think of a better time to waste hours and hours - and this is coming from someone who does a lot of that. Believe me, you'll thank me in the end.
