The plot was entirely predictable from start to finish. The bad guy was lame and never once interested me. But the action was fine and the character development was good to see.
Overall, I think it's a great movie for a different reason. It has finally gotten away from the shackles of the original movie trilogy and it's cast. By the end of X-Men Apocalypse we finally have our entire new cast of characters with new actors all assembled and they seem really good.
I feel like the stage is finally set for the next X-Men movie to potentially be great. I think this cast can do amazing things if given the right script now that they're finally free from all the baggage of the first three X-Men movies.
So, while I don't think I'll be re-watching X-Men Apocalypse anytime soon instead I'm super excited for the possibilities that the next movie in the series will bring.
