I only recently started rating stuff on my list, and I don't want to rate anything that I haven't rewatched since starting up the ratings, hence I've given out very few. A ranked list of all the anime I've rated is here.
My 10-scale can be read something like this:
10/10: An all-time favorite that I hope to revisit for years to come. Most likely appeals to me on a conceptual level.
9/10: Still one of my favorites, but not quite as dense with things to love, or has moments that I might not have loved.
8/10: Very cool shows that I enjoyed from start to finish, but didn't quite appeal to me on the raw personal level. Still stuff I'm likely to revisit.
7/10: Shows that I overall enjoyed and could see watching again, but wouldn't go out of my way to do so. Probably had some things that bothered me, but nothing to make me hate it.
6/10: Doesn't really appeal to me, or was filled with problems, but overall I still was glad I watched it. I'd probably never rewatch these of my own accord.
5/10: Didn't appeal to me enough to feel like it was worth my time. These shows aren't offensively bad, but if I could tell my past self not to watch them, I would.
4/10: Actively boring shows. Maybe had enough moments that I liked to keep them from being the worst thing ever, but overall I just regret watching them. At this point, it becomes extremely rare for me to finish anything that I dislike this much, meaning that most of the scores from here down will be on movies or shorts.
3/10: Trashy, boring shows. The kind of stuff that might have one appealing attribute, be it artwork or a certain character, but overall it's not enough to salvage it.
2/10: At this point, I'm passing out watching the show. It's either unwatchably bland, or outright bad, and nothing is strong enough to save it.
1/10: A special place reserved for shows that aren't just awful, but also offensive. If I feel disgusted with a show by the time I'm done with it, this is where it goes. Also home to shorts that I felt had nothing in them at all.
