I enjoyed this film. I don't get why its getting the hate from the critics. It's not a great film, but its enjoyable. I liked Oscar Isaac as Apocalypse. I thought he mostly got the character. Many of the newer actors, despite some screen time or story problems, were mostly watchable. I didn't care for Sophie Turner as Jean Grey. Physically she fits the role perhaps more than Famke, but I felt she was bland in the role and the story kept holding her back to have that one big moment for her.
I do agree with the criticisms that it was overstuffed and a lot of the characters got lost in the shuffle. One of the most egregious was Jubilee. I mean this actress was making the promotion rounds and was barely in the movie. Alexandra Shipp, the Storm actress, was also promoting this pretty hard, which doesn't match the development she got. I also thought more could have been done with Storm, Psylocke, and Angel.
Nightcrawler too, but I wasn't too miffed about NC's screen time, or lack thereof. It was the Horsemen that largely got the short stick. I actually liked the ancient Horsemen more and wished they had keep them around instead.
Visually I though they hit the mark with the New Horsemen, though the Psylocke costume felt a bit too unrealistic to me. And thought Magneto's had too many lighter highlights.
I also thought the inclusion of Moria McTaggart felt off. I wish she had been in Days of Future Past instead. And it bothered me how the film handled how Charles's altered her memories. The film didn't have enough time to let some character moments breathe. I also wasn't as jazzed for the Weapon X cameo as I should have been. For one, they revealed Logan's inclusion weeks before so the surprise was gone (unlike the excellent First Class cameo), and I just didn't feel that Jackman was feral enough.
I also felt this film didn't do a good job inhabiting the 80s. First Class and DOFP were weaved into their respective decades and tied to actual historical events. I wish Apocalypse had done this as well, showing us the secret history. I was really stoked by that aspect of First Class.
Despite my criticisms I thought this was an X-Men entry that was not embarrassing. I do think though that Singer has reached the limits of his creative vision and I think they need a change in directors.
