I don't really like the show Glee, but I watch it.
During the first half of the first season, I was a champion of the show. (Not of the blog, so much, but when asked about it in real life. For a while it was my favorite show on TV.) It was about this group of kids trying to find a place to fit and even the place where they best fit wasn't comfortable for them. It was about the formation of a team coming together to work toward a difficult goal. And surrounding this theme were interesting characters, backstabbing, a cute and earnest OCD teacher, a psycho with a fake pregnancy, The Pink Dagger, and the always utterly fantastic Jane Lynch. Oh and lots of great songs. (These span the whole of the first season. Dammit.)
When the second half of the first season came around, something seemed to change. The music was still great, but the characters weren't right. They all seemed so much more over the top. And while that worked for Sue Sylvester, it didn't work so when for Artie or Tina or Brittany or Will. Stories also became about the topic of the week, not the characters. I kept watching, though, because of the songs. It's like horrible train wreck, death and destruction, gorgeous sunset, train wreck, death, amazing painting, train wreck.
After moving, I didn't watch much TV until my brother pointed me to the D&D episode of Community. That's when I went back to my unhealthy hate/love relationship with Glee. It still has all the same problems (although I've been pretty impressed with the Santana arc in the past few episodes), but I can ignore them more. Now I just watch it episode to episode and don't expect anything to really carry over from one episode to the next. I just enjoy what's there. It's become a lot easier to watch.
And that's why I keep watching, even though I'm pretty sure I hate most of the show.
