What? None of those rules applied to all comic book films, and they got less and less broad as the list went on. "The villain must redeem himself"? Where heas that ever been found outside the Spider-Man franchise? (And Mystique does not redeem herself, she gets back at Magneto for ditching her after she saved his life)
B89's origin story was not even close to tedious, by the way. It was one of the better-crafted handlings of a hero's beginnings, letting the audience be vicarious participents through Vicki Vale in discovering more and more about Batman's character as the film goes on. And it only tells us the bare essentials, leaving the tedious details by the wayside and leaving much of Batman in isolation and mystery, just as he himself was.
