I am definitely looking more forward to Apocalypse than Days of Future Past. So i can't wait to hear more news about it.
From what little has been hinted it's going to be an disaster epic and delve into themes associated with Apocalypse. He is one of the greatest X-villains and fascinating character to build a grand scale story around. I like that they are going to explore the idea of mutants being perceived as gods through out time. Maybe we will get to see some fun hints about who in history could have been a mutant. Like Joan of Arc, or Leonardi Da Vinci, or Pocahontas?!
I also love that it will be set in the 80s, which hopefully means no Wolverine but maybe finally the inclusion of a new Storm, Cyclops and perhaps Jean Grey. They also mentioned including Nightcrawler and Gambit might find their way in the story but not sure how or why but maybe we can see other new mutants on the team. I could also maybe Magneto and Mystique joining forces with Apocalypse but in the end betraying him to help save the day like in X2.
What I imagining is already getting me excited especially if the set the Apocalypse in Egypt, then we could maybe get a small Storm origins in the movie, since she has fits in so well into the themes and settings of the movie. As a child thief in Egypt, then mutant goddess in Kenya, and a second genesis X-men. It would also be interesting if they bring in Jean as well and hint at the Phoenix, which could the yin to Apocalypse's yang.
I just want to see the next movie be about the X-women, for once. It's been too much about the same characters and we need to get to what made the X-men great, equal empowerment of all the characters.
