10s (A+) Top notch shit, very memorable, and leaves a lasting impression on me
9s (A) Awesome shows, notch under masterpiece, usually lacking some oomph to take it over the edge
8s (B) Good shows, they stand out. Consistently enjoyable.
7s (C) Above average shows
6s (D), Average, there are lots of em, didn't do anything special, neutral towards them.
5s to 2s (F) Bad - Very Bad - Terrible - Garbage Shows that I see as stupid, boring, but mainly stupid, since if its boring, I would drop it
1s (Go Fuck Yourself) Cancer A score more special than 10s, shows that have no redeeming qualities, or shows that are so bad, that even when I dropped them, they had a lasting impact on me.
Crap I don't drop in the middle of episode one don't get added
For Manga/LNs or books in general, I can ignore quality of earlier books/chapters, most of the time, the author starts off weak, then as time goes on, the series usually gets better especially in novel series.
I only read stuff that catches my eye, nor am I that critical when it comes to them. Why would anyone read something they don't enjoy for fun?
