I think this is a good point. It feels like they never expected to get picked up after the initial order, and then had to rush and come up with more episodes. The latest episodes just feel like they aren't quite finished, and are missing that last bit of polishing that they need. I wonder if some of the writers changed. No matter what, there is a different feel from the last couple episodes. The characters are just slightly "off." This new storyline with Jesse is stupid. He's such an obnoxious douche that I can't take him seriously as a character, and can't believe the storyline with him and Rachel at all. Even as ridiculous as high school kids are, and the leeway I give the show when it comes to realism, it just doesn't work. At least in the early episodes, the characters and storylines seemed somewhat like something that could exist in a high school. Now, that awkward "high school" feeling is quickly disappearing.
