How I rate anime is mostly based on my enjoyment of it, thus why I have so many 9/10 and 10/10 ratings.
10| I really enjoyed it, I found that it's a really beautiful anime, it was so well-done, i liked opening and ending or I simply loved it a lot
9| Either means I enjoyed watching it, But not as much a 10/10 anime, or because I simply didn't like it as much as a 10/10 anime.
8| I enjoyed it, but not as much as a 9 or a 10.
7| I enjoyed it but there were some parts I really hated. Though there are some exceptions.
6| "Maybe" I enjoyed it but it was really bad, or I just don't care about this anime.
5| Is awful, really awful.
4| K. That's a big no no
3| Ehhh Shine..
1| U know better is probably boku no pico
