Hi, there! I like to draw, I'm a big anime fan, and I have autism! It can be difficult at times, but others, it lets me hyperfocus on things (which can be good and bad; it's good if it's something enjoyable, and bad if it's something scary).
I believe this is the reason my anime tastes change so often; every couple months or so, I get a new favorite anime. Sometimes, animes that used to be favorites of mine resurface, and I focus on those. Focusing on it means writing and drawing, too.
Actually, if it wasn't for anime, I never would have learned how to draw. And the ability to hyperfocus, too. So, in this case, I'm thankful for both. ^^
I'm a really harsh critic on anime, and something has to really wow me to get 5 stars. Some animes, I can't remember what they were about, so I either didn't rate them or gave them a generic 2-star rating. If they can't leave an impact on my mind, it's not worth much.
I take plot, characters, and re-watchability value into rating an anime. Do the characters develop? Does the plot work? Does it fall into "Dragonball Z Syndrome" and get overpowered? Is it clear enough for people to understand?
Those are the things I consider when I rate an anime. If I enjoyed it a lot, I'd recommend it. If it's taking too long to get to the main point, or there are mysteries that should have been explained or at least hinted about seasons ago, the rating goes down. If the plot gets static and the characters don't grow, I typically drop an anime. I also drop anime or manga if it doesn't interest me like I thought it would.
I'm currently in the process of writing more reviews for anime I've seen both in the past and recently. Since I've been watching anime since the 90's, that's a lot of ground to cover. XD
