This post is just about the portrayal of this one character. The film overall was a bit of a letdown but that's not what I want to focus on.

As a villain, Apocalypse left alot to be desired. He was not very physically imposing (I think he was shorter than some of the other characters lol) and the blue prosthetics were just cringe. I like Oscar Isaac but, that voice is just not how I'd imagine Apocalypse after reading the comics. Suitable for another role, just not this one.

Also, he lacked alot of the superpowers that made him compelling to me. The shapeshifting, the ability to grow to gigantic sizes etc. The trailer promised some of the latter but that ended up just being bait.

The scheme to get him to posess the world's most powerful telepath is actually not bad. They were fine keeping that. I wish the film did a compare / contrast with Magneto since his (Apocalypse's) are probably more extreme than Erik's.

How would I change him?

1) Cast an actor who is 6ft or 7ft. I'm talking The Rock or John Cena. If not them, then another charismatic wrestler.

2) Make him grey / pale. Not blue. He doesn't have to look like a raisin.

3) Give him more his more creative superpowers. I want to see him grow claws and lasers for hands. Make him actually grow to giant size. He was overpowered in the comics, but at least his powers were memorable. Not like this guy.

4) Maybe have this film set in the 1980s be the one that gives Erik the idea to kill / subjugate humans in the 2000s. If the prequel plan was better, you could have it that young Erik just wanted mutants to live separately to the oppressive humans. But then Apocalypse grooms / influences him into thinking that peacefully separating from humans (like on Genosha or Asteroid M) doesn't work, you need to destroy them.

Any other changes?

How would you have changed Apocalypse in X-Men: Apocalypse?
