I really liked that last paragraph about the consistency of the characters. I have always felt that exact same way. So many things twisted and turned to fit the moment. As a result, just about every character turns out to be some kind of extreme asshole or another somewhere along the line. One minor example is, Dwalla is totally into Billy, then she brushes him off for Lee, then he dies and she shrugs it off, almost like "Well, now that my ex-boyfriend is gone, I can go after this new guy guilt free", then they get married, and Lee cheats on her with Starbuck, then they break up, then they start to get back together and she splatters herself all over her locker.

All these sharp turns took place just to serve the episode in which they took place, almost as an after thought. Consistency was sorely lacking throughout.
