X-men: Days of Future Past

I love X-men. I love film. So naturally, an X-men film almost guarantees my attendance. The latest in the series was X-men: Days of Future Past. It was quite enjoyable, as I love the majority of the cast and there's nothing more satisfying to me than a good ol' mutant battle. There were just a few things bugging the hell out of me, this one point in particular:

I mean, I'm not looking for direct comic-to-movie adaptation. I love new interpretations of classic storylines and scenarios. The thing that bugs me, though, is when liberties are taken simply for the sake of telling the director's story. Creating this random power for the sake of time travel made absolutely no sense. When the hell did Kitty Pryde develop such a gift. In the original comic, Rachel Grey (a telepath) was the one who sent Kitty back in time. Now, I get that in the movie universe Kitty would have been way too young to go back. However, Professor X is still alive (unlike in the comic). All-powerful telepath sitting right there the whole time. There was no reason to go artificial. They could have just swapped out Rachel for Professor X. If someone could give me a logical reason why that didn't happen, I'd love to hear it.

Atkins out.
