1.) The old cast still play well as their characters (I especially like that Quicksilver gets a bigger role in this movie). Some of the new cast members did great playing either new characters or younger versions of those characters (although, there is a problem with the characters that I will get to in a moment).
2.) Apocalypse does a great job giving a huge sense of urgency and distress. What he does and what he plans to do give good enough reasons to have many think why he is such a huge threat not only to the X-Men, but the entire world.
1.) There are too many plot lines to follow. It is not too many to the point where it is unbearable to watch, but it is distracting. (SPOILERS) For example, somewhere around the second act, the movie somewhat ignores Apocalypse, and instead concentrates some of the X-Men being kidnapped by Col. William Stryker. (END SPOILERS)
2.) The CG is not the worst I have ever seen, but they are not exactly good. It looks like it came from a working graphics beta stages of a video game (and I am being a bit merciful on what they look like).
3.) There are so many convenient moments and plot holes in the movie that it baffles me. One example is how four mutants (including Magneto) join Apocalypse. Long story short, I am not buying why they join him. Some of the characters are not even used well. Two examples are Jubilee and Moira MacTaggert. These two are not needed, and can be erased from the movie with little to no consequences.
After the success of X-Men: Days of Future Past, and rebooting the entire X-Men movies, it was inevitable for 20th Century Fox to go in for a sequel. Who was going to be the villain? Answer: Apocalypse. This interests me, and I wonder how they are going to deliver this. I can tell it to you like this: X-Men: Apocalypse may not be as bad as X-Men Origins: Wolverine, but it is not as good as X-Men: The Last Stand. Short story: I did not like it. At first, I thought it was fine, but the more I thought about it, the more I see the problems in this movie. As I said, it is not the worst X-Men movie ever made, but it is one of those movies that had potential, but squandered it. I hope it is not the start of the studio milking the franchise as much as possible, otherwise, as Apocalypse said, “Everything they built will fall, and from the ashes of their world, we will build a better one.” Wait. Apocalypse sounds a bit like Marvel Studios.
