Batman isn't a powered super hero, but he is supposedly the greatest detective mind in comicdome. That makes him pretty super.
His ability to invent is on the Tony Stark level too which would make him also pretty super.
I see your point, there have been some real stinker comic movies. Any of the original Batman movies after the first and excluding the last were just awful. The one with Clooney was one of the worst movies ever made let alone genre pieces. But there've been some good ones too. X-Men and the second one were competent. The first Batman with Keaton, Spiderman wasn't bad at all.
