Well times have changed, comic storyline change. Hell Wolverine original origin idea was that we was in fact a mutated wolverine, but they changed it. Emma is a huge part now. Plus though it hasn't been explained or mention, but in the original Origin miniseries it is alluded to that James's half brother Dog, could be Sabertooth, I am not saying he is but when Dog comes back he does bear a striking resemblance to Sabertooth. Anyway by now you should be used to the way films change stories from comics. Get a grip man, if you don't like it that is completely fine. So far the only aspect of the film I am really not liking is how they changed Deadpool, all the other aspects I can deal with. And yes I am or was a huge fan I know the history, I know Sabertooth comes on Wolvie birthday every year to kick his ass, I know they are mortal enemies, I know who Deathstrike is.
