I currently use MAL's rating system.

10 = I thought it was a masterpiece

9 = I thought it was great

8 = I thought it was very good

7 = I thought it was good

6 = I thought it was fine

5 = I thought it was average

4 = I thought it was bad

3 = I thought it was very bad

2 = I thought it was horrible

1 = I thought it was unwatchable

Outdated: 
My rating system is taken from Goodreads:
5 stars - it was awesome

4 stars - really liked it

3 stars - liked it

2  stars - it was okay

1 stars - didn't like it
