I thought season 2, the first half of season 4, and season 5 were all fun. Season 3 back in prison wasn't as good but sets up all the characters for season 4. Season 4 has way too many gotchas and just keeps dragging on. Would be much better as a 12 episode season. Season 5 was fun and fixed the dumb ending of the TV movie. Definitely silly, but overall it wasn't as terrible as everyone makes it out to be.
