I started watching anime pretty "late" (comparing to the common age when people start watching anime) but that doesn't stop me from enjoying in them :) I started reading manga even later (in 2014) but it's really an addiction :) I like this site because it helps me to keep a track of what I've watched/read and it's a great help for the times when I'm deciding what I want to watch next. And if I get to meet some new friends while I'm here, that would be even better :)
As for the scores, it's pretty hard for me to give scores. I definitely need a more divided system, with scores like 8,5 and 9,5. I have anime that they both have, for example, a score 8 but I liked one more than another. Anyway, the ones that have 9 or 10 mean that I will watch them again (or I already watched them again) because I like to rewatch the anime I liked a lot. Basically, every anime that got an 8 or more from me, I really liked and I recommend it. I "judge" them subjectively...based on the emotions they awaken in me or how much they entertained me or made me laugh or made me sad. I'm also a sucker for beautiful art, colors and music. The ones that got 7 are pretty nice but you will survive if you don't watch them and there are better things. Still, not so bad. Everything from 6 and down is just something that I kinda wouldn't suggest (maybe some rare ones that have 6, if you really insist). I don't like to bitch a lot about anime and criticize everything, I have things I like and I have thing I dislike and I have my opinion about it but I don't talk trash, neither I like that. I like various genres (some way more than others), but of course, there are some I'm not a fan of.
More and more, I am in search of "special" anime or manga, that will interest me, that are different from all those other "generic" and repetitive ones, or different in their own way inside of their own genre. There's nothing better than finding those jewels :) If you have some suggestions, I'm all ears! :)
