The moment in X-Men 2 when people are talking Xavier's schools and Wolverine unleashes his claws and stabs a dude through the chest. In the cartoons we were kind of stuck with him mostly slicing through robots and stuff and even the first X-Men movie avoided the idea that they're flesh-cutting weapons. So to finally see his brutality from the comic put up on the screen was exciting. My theatre went silent, then erupted when that happened.
