Well he has killed villains in the book and his earliest incarnation used a gun as well before the post-Silver Age era DC finally set up a Myth Arc for the character. Besides, I'm cool with the different media's putting their own spin on heroes and Tim Burton needed to make the films darker than what people expected to get comic book films out of the animation ghetto so to speak.

X-Men 3: The Last Stand will always be the film that really hurt me as a fan. While the first two X-Men films were not close to what I wanted, they made the most of what could be done back then and I was just happy to have an X-Men movie but this film was just awful and I really wish X-Men writers would finally get over the Phoenix Saga. Wolverine: Origins and Batman and Robin are the other two really awful comic book movies I've seen.
