10: Masterpiece! Simply perfect. I've anything to complain about the series.
9: Amazing! ALMOST perfect.
8: Great! Very good anime, with some flaws, but still very good.
7: Good! It's good, but not THAT good.
6: It wasn't so painful to watch, but still boring sometimes.
5: I was really hoping for it to end.
4: The worst of the worst.
Anything who could have a rating lesser than that, is instantly dropped. Or I completely hate the show, like this shit.
