I dont know why this movie is the worst reviewed from the franchise. I think its better than Xmen apocalypse. It might be a bit slow in the second act, but it picks up and the actors save this movie. Given the production problems and reshoots it ran across i think they did a great job making it watchable. The story is simple and by no means its deep, maybe here is where it failed the critics, because it doesnt make you think. You just follow the adventures of the xmen trying to deal with this new menace. Keep in mind this is the first time Kimberg directs a movie, and more so a movie of this caliber.
