I'm a huge, long time fan of Arrested Development. I've watched the series from the beginning, I've actively followed the revival developments since 2006. Which is why I will say this, even though it pains me to do so: Season 4 was kind of a let down. Sure, it was great to see the old cast and characters again, but what made AD so great is that it's an ensemble show, and the cast played off of each other so well. You take that out of the equation, you're not left with much. Now that said, if there's a season 5, I hope they make it as good if not better than season 4.
