Most of my ratings are based on my personal enjoyment of the series and not necessarily on the quality of series. There are a number of series that I will agree aren't the best, but that I personally enjoy for whatever reason. If an anime keeps me entertained enough to want to see it to the end, I'll likely rate it pretty high.
I've been interested in anime for a while but didn't really start getting into it until more recently, so there are still many series I haven't seen yet.
I mostly watch sports anime and other more realistic/slice-of-life anime, but also enjoy fantasy and other genres. I'll give pretty much anything a chance at the very least, although I refuse to watch anything with heavy gore or ecchi.
Aside from that, I don't know what else to say here.
