10 Sci-Fi Movie Endings That Get Worse The More You Think About Them
2. Everyone Is Dead -- X-Men: Days Of Future Past (2014)
X-Men: Days Of Future Past represents a definite high-point for the series, coming off the back of Matthew Vaughn's sublime reboot First Class, original series director Bryan Singer took the reins and delivered an X-film that brought together casts old and new for a time-hopping romp.
Professor X (Patrick Stewart), Magneto (Ian McKellen), Shadowcat (Elliot Page) and Wolverine (Hugh Jackman) are among the last remaining mutants in a bleak, dystopian 2023 (not this one!) where Sentinels have all but wiped out mutantkind. Thus, they send Wolvie back in time to stop the events leading to this future.
The ploy works and a paradigm shift emerges, circumventing the creation of the Sentinels and separating these films into a new continuity from the original series (2000-2006). While they may have thought they were "resetting the timeline", established Marvel comic and movie lore dictates that all they managed to do was create one of many alternate timelines -- something backed up by the existence of Logan (2017), in which Wolverine and Professor X are alone in a barren 2029 where mutants have been hunted almost to extinction.
Thus, while different versions of the characters get to live different lives, just about everyone from the original timeline is dead; they didn't save themselves, they just created another strand in the multiverse.
