No, just no.
X men is not wolverine, it is display of the power of the mutants. Every single movie titled: X-men has a saying: “be the better man”.
You cannot just base every story upon the fact that one part of the mutants wants a war with humanity and other part doesn’t.
X-men first class was good not cause of what happened in the Island but because it showed something different with the training and history of X-men!
I am just tired of seeing professor Xavier trying to stop Magneto even if it is in the past. So disappointing!
It’s okay as a standalone movie if you haven’t watched the series.
