The X-Men franchise is arguably the best superhero series still going. I’ve said that in the past as well. They were putting multiple characters with super powers together long before The Avengers. Every movie has been great except X-Men: The Last Stand.
The newest trilogy which features the younger versions of staple heroes/villains has far exceeded the first three. Growing up watching X-Men: The Animated Series in the 90s, Apocalypse is the villain I’ve been dying to see appear in the films. CGI has evolved enough to make it happen without it looking shitty.
