In X-Men: Days of Future Past, Wolverine wakes up in the future and sees that all of his friends are alive and happy. This means that not only do they survive any remainder of the film that remains...they will also survive X-Men: Apocalypse and any future sequels until the timeline eventually catches up. There is ZERO drama about Beast, Rogue, Iceman, Cyclops, Jean etc in the upcoming films. They will survive whatever threats they face, and they will win a decisive enough victory that will allow them peace and happiness in the future. It has turned the entire X-Men series into prequels, forced into being in line with that future scene. I loved the film when I saw it, but as time passes this detail eats away at me more and more.
