10 - Masterpiece. Peak content, and it really doesn't get better than this.
9 - Outstanding. Very close to 10, but just not quite on the same tier.
8 - Excellent. Very good content, and can make you feel emotions. Would certainly rewatch and recommend.
7 - Good. Enjoyable to watch.
6 - Passable. Probably wouldn't rewatch, but time isn't wasted by watching it.
5 - Mediocre. Very average content, and wouldn't recommend.
4 - Unacceptable. Not good content, and gets to the point where it feels slightly uncomfortable to watch.
3 - Bad. Gets to the point where it feels like time has been wasted.
2 - Terrible. Gets to the point where it's difficult to finish, but not quite as bad as 1.
1 - Insulting. The worst conceivable content. At this point, it's stopped being watched. It has absolutely no redeeming qualities, and it's unable to be watched to the end without feel insulted or angry.
