Days of Future Past
The X-Men movie universe, much like the comics, have a loose relationship with the concept of time. Wolverine Origins and Last Stand were films that few people could admit to liking, and after First Class turned out to be genuinely great, the folks at Fox were put in a position where a reboot was the only way to go forward. And what better way to reboot than with a convoluted time travel plot?
Days of Future Past isn’t as good as it could be, but also fun enough to overlook its flaws. Putting Wolverine from the near future into his 1970s body (don’t ask how that works on any level) is a good hook to reunite James McAvoy’s Professor X and Michael Fassbender’s Magneto after the events of First Class. The stuff with Quicksilver, however brief, is also a highlight, and the Sentinels eventually get to be an alright presence.
But those problems, man. They’re there, and when you think about them, they really don’t make sense. Eventually, you’re going to wonder why they made a big deal about reuniting Charles and Erik to stop Mystique when only the former actually manages to get through to her, or why the team even travels to Paris at all. If you can get past issues like those, Future Past will satisfy, but even with that in mind, it isn’t as good as it could be.
