The worst thing about Scrubs 2.0 was that it could've been actually good for several reasons:
1. Zach Braff should've only appeared in the first two episodes. I have two reasons for it. One, you screwed the audience over into thinking it was going to be about JD. They should've just handed to the torch in one or two episodes instead of six. Second, JD was more annoying than ever. Its like he regressed even worse than the some of the episodes of Scrubs 1.0.
2. Lucy should've never been the main character. Even though I will admit she was cute, that won't make up for her being unfunny, and the actress having none of the comedic timing nor charisma that JD had. Before Scrubs 2.0, Lucy was described as having JD, Eliot, and Turk fused into one character, and while I saw no Turk in her, I saw mostly only the negative qualities of JD and Eliot.
3. Drew should've been the main character. Drew was the best thing about Scrubs 2.0 whose name wasn't Perry Cox. Not only was he funny, but he had a more fresher story than Lucy that would've been more original.
3. They should've had better supporting characters. I don't mean the major ones like Denise and Cole (to be honest he was getting better). But I'm talking about the more minor ones like the security guards. Look at the lesser characters they had to replace.

Are these same writers that written the earlier Scrubs seasons? The show hit its peak during the last season and they didn't need to come back with another season. I really hope they cancel the show. The only way I would watch it now is if they didn a complete revamp and made Drew the main character.
