X-Men: Days of Future Past is a miracle of a comic book movie. Not only does it right the franchise after a majority of fans lost faith in it, but it also takes a cinematic eraser to some of the series’ low points.

By the end of Days of Future Past, dead characters are revived, lovers reunited, and entire movies are gone in the blink of an eye. To help you make sense of how the new timeline completely tramples on the old, we’ve distilled the whole thing down to this: Five Ways X-Men: Days of Future Past Fixes the Franchise’s Previous Mistakes.
