As far as the VFX is concerned, the movie is really awesome. Now to the story line. Like the last few xmen movies which were released, this one takes place in the past with the mega villain
Apocalypse. But there are many unanswered questions in this movie as to why the super villain doesn’t destroy everyone because he can do it easily without much hassle. It just shows one of the flaws in this movie. Apart from the plot related issue, the movie seems fine.
