And you have folks saying Logan isn't actually part of the previous X-Men continuity....which is saying that Force Awakens really isn't a sequel to the original trilogy. SO WHY SHOULD WE GIVE A DAMN ABOUT THE MOVIE OR THE CHARACTERS? The whole thing depends a lot on the audience's previous connections to Logan and Xavier.
That isn't a fair comparison based on Days of Future Past. TFA is most definitely a sequel, just set 30 years later than ROTJ instead of picking up a short time after. Logan takes place later in the timeline than the "future" we see in Days of Future Past, but I don't think it goes into detail if it is the altered future which erased the events of X-Men 3 or if it is a different timeline.
I thought Logan was a great movie. But at the end of the day, it needs to exist in a timeline where the events of X-Men: The Last Stand, X-Men Origins: Wolverine and The Wolverine all exist.
I know it wasn't in the final cut of the movie, but in a deleted scene, set during the dinner at the farmhouse, there is a mention made of Jean Grey and that Logan loved her and he had to kill her.
This means that, as originally scripted, Logan does NOT fit with the more hopeful ending of X-Men: Days of Future Past, because that movie negated X-Men: The Last Stand.
So I think the first three X-Men movies and the three Wolverine movies all go hand-in-hand. It's almost like they exist in a movies timeline where the X-Men: First Class movies never happened. Once you introduce those movies though, it starts to negate
A lot of people didn't like the inclusion of the Weapon-X scene in X-Men: Apocalypse because if didn't fit with the fact that in X-Men: Days of Future Past, the last time we saw 1975 Logan, he was getting rescued by Raven/Mystique, so how did he end up with Stryker in the Weapon-X program?
I theorize that X-Men: Apocalypse further splinters the timeline because of that Weapon-X scene and sets everything from Apocalypse forward on a timeline totally unconnected from the "happy" ending from Days of Future Past. This way the creators of all future X-Men movies, especially those with the McAvoy/Fassbender cast, can totally ignore all of the previously released movies with the Stewart/McKellan cast and branch off in a totally new/fresh direction.
