MCU X-Men: 5 Things Disney Must Learn From Fox's Movies

5. Broken Timelines Are Not Fun

When it comes to Fox's X-Men films, it would be foolish to say that there is one solid timeline. The movies featuring the younger cast blatantly contradict the original films, which makes sense after the timeline was reset in Day Of Future Past, but it was happening even prior to that, with the flashback scenes in the initial trilogy showing Xavier and Magneto being friends for far longer than First Class showed.

Little things like this, as well as more egregious examples, such as the three different versions of Emma Frost, simply mar the viewing experience and, sure, most of these movies are enjoyable in their own right, without audiences having to pay much attention to the timeline.

For a collection of movies that are supposed to exist in the same continuity, however, wouldn't it make more sense to just make sure that the films actually fit into the same puzzle?
