It took me a while to get around to watching Arrested Development but when I've finally gotten around to it two years ago the first thing I did after finishing the series was starting a rewatch, the show totally delivered. I started it for the third time a month ago and I'm currently in the middle of season 4, actually watching GOB's episode right now. Season 4 starts off rough but GOB episodes are so damn good.
I think I actually prefer season 4 to season 3. Season 3 just feels a tad... forced? I guess. I really dislike british arc (even if it ends with the best scene in the entire series, as already mentioned in the first two posts of this thread) and other episodes aren't much better, in the trying-too-hard way (especially Tobias' hair plugs were too much for me).
