Now that I've seen it I can say I was truly prophetic when I made this:
Alright, it's not a bad film per sé but it just has nothing going on for it. For every good scene there's a shytty one, and for every good and shytty scene there are a dozen that fall completely flat. Magneto's character arc is laughably bad, yet it's still the only one that still feels like it matters, Apocalypse is as shytty as we all felt he was going to be and at no point did it feel like Oscar Isaac could salvage it. Then again, nobody gets anything to work with so first class actors (pun intended) like Fassbender, McAvoy, Lawrence and Byrne are practically sleep walking through this. It makes for a movie that never feels like you should care for anything that happens in it, not the worst crime but certainly the most boring one.
