I kind of disagree, but kind of agree. When I saw it in the theater I was the same as you were: bored out of my mind. Then, for whatever reason, over the years I started to like it a lot more, to the point now where I look on it very fondly. I'm no longer bored by it, and for some reason the cheeseball stuff is endearing to me. It is definitely overrated, particularly considering it was considered by many to be the best comic book movie until TDK (although I like Batman Begins better than SM2 as well), but I just wouldn't personally call it boring.
