Why would it be though? That's the great thing about super hero movies, you can just keep making them, and people will still see them.
Look at Superman 3. What were they thinking!?
I didn't think they'd let it die, but everyone kept saying that this would be the last X-men movie.
Oh, and I think Superman 4 was worse than Superman 3. At least Superman 3 had Richard Pryor making it somewhat funny.
Which one was 4? I don't remember it.
Man, Supergirl was bad, that was just the worst of them all.
4 was the one where Superman throws all of the nuclear weapons into the sun. Imdb link:
Oh yeah, I remember, that blonde guy from the sun. That was lame.
