Honestly, after season 5 I just couldn't really watch the show anymore, it was like they were trying to hard to make you laugh with real bad jokes.. The storyline in some of season 4's episodes were good, but not that funny.
I agree the show has a lot of potential, but I don't see the potential being in comedy... It'd be strange, but I'd definitely have liked them to get more serious with the characters and make a season devoted to a captivating storyline.
