To those few who are interested, I rate anime mainly for my own amusement. Score represents what I felt immediately after finishing series, rarely I dont differ from that score. If I do, its usually only one digit to better or worse.
Also I wont give rating to anime if I havent finished it, so no rating for on going, hold or dropped anime. I dont skip episodes either so if I havent fully seen anime, I cant give rating for that.
About how I rate anime... Well im easily impressed and appreciate various aspects of series. Thats why I have lots rated 7 or 8, even lot of 10 compared to most users. I dont have basic lets say 5 different points (for ex. Plot, Character, Sound, Animation etc.) and calculate score from that, but I rate series whichever feels appropriate.
Basically everything ive rated 6 (of course with a pinch of salt) or above I can recommend to watch. Not every one below that, even close to 1 isnt trash-tier, maybe some of them needs proper rewatch, but whenever Im gonna have time for that?
