Did you like the other X-Men movies?
Bryan Singer directed 2000's X-Men, the sequel, X2, returned a decade later to helm X-Men: Days of Future Past, and resumes the position for its sequel. To frame my own feelings, a from-the-gut, worst-to-best ranking: X-Men Origins: Wolverine (2009), X-Men: The Last Stand (2006), X-Men (2000), X-Men: First Class (2011), X-Men: Days of Future Past (2014), X-Men: Apocalypse, The Wolverine (2013), X2 (2003). Thoughts?
Like Singer's previous entries, Apocalypse spins 15 plates at once, harps on the thinly veiled mutant-equality debate, and pushes the superpower action as far as CGI can go. But if you're emotionally attached to the past, Apocalypse will aggravate: the movie glosses over the future determined by the original trilogy, disavows The Last Stand and X-Men: Origins, and plays fast and loose with a timeline established in the previous two movies. Screw logic! Apocalypse wants to cash in on recognizable characters and live in a 1980s bubble. Play along and you'll have a blast.
