As UsuallyDead said in his review...
"I like this show because it's mostly fluff and good feelings. It's all moe, without any deep meaning or symbolism. The entire show just screams 'We're high school girls playing music! Isn't that just great?' Yes, girls. Yes it is great. I'm a 20-something year old male, but I'll just sit around and watch your adventures. Now go through high school, girls... There's nothing pathetic about me. No sir."
I agree with his "Gah! WHY DO I LIKE THIS SHOW?" attitude.
Then again, it's a good show...
I loved that show~
