I haven't/don't read comic books. It's not that I have anything against them; there's just too much history and backstory at this point so it doesn't feel worth it to start reading now. (That's what Wikipedia is for, anyway, the backstory condensed.) I'm sticking with the movies and occasional TV show.
But geez this was one of those *yawn* of a movies. I'm not sure there's really much tension if no one is genuinely at risk in these fight-for-the-fate-of-the-world movies. All the main characters come through unscathed and unchanged, except for the random hairstyle change. Looking at you, Professor.
I really wanted to like this episode of angst-y teenagers with random superpowers and their oddly-aged adult cohorts. It's a good cast of actors and everyone does a good job. But here's my random thought: the X-Men powered people rarely interact outside of their little group. It's powered against powered against powered. Even the big destroy-the-world scenes did little more than show cities falling apart but I didn't connect to the citizens. At least the regular Marvel universe movies throw in non-powered military and government entities to connect to the real world.
I can't think off the top of my head of anything terrible about "X-Men: Apocalypse." Maybe one quibble is the odd (to me, non-comic book reader) intro to Storm. Thankfully the theater where I saw it had a pre-roll "Thanks for watching" with the actress who plays Storm and named her character in the lower third—that's the name tag area under a talking head. I learned that from when I worked for a TV station.
