My ratings are based on a combination of enjoyment, my opinion on the objective quality of the work (plot, characters, art, music, execution, etc.), and the work in context of its primary genre(s) if any. (<INSERT GENRE> as a -type story and compared to other -type stories.) Sometimes one of these factors wins out over the others.
I tend to have very little patience for any anime that I don't think is at least going to be a 6 or 7+. That being said, my anime ratings are a lot higher than my manga ratings, and I tend to be more lenient with anime in general because I don't watch as much of it.
I am also more lenient with oneshots and OVAs, given the relatively short amount of time in which to tell a story.
