Re: This Franchise Needs a Reboot Bad
X-Men movies will continue in some shape or form, whether some people here want it or not.
In order to retain the movie rights, Fox must make new X-Men movies at regular intervals, so it will do just that (unless, for whatever reason, the rights end up back at Marvel). At some point a reboot will become necessary because none of the existing cast will still be suitable for the roles. They could just recast and move forwards but at some point they will feel the need to start with a clean slate. Whether the franchise goes right back to the beginning and retells the same stories is another matter.
In just the same way, there will always be Superman and Batman films - because studios want to make money AND because creative people feel the urge to tell a story with those characters. There have been Superman and Batman movies since the 1940s.
As we can see by the upcoming Superman vs Batman project, they have no intention of just leaving Batman alone after Nolan's acclaimed, self-contained trilogy.
It won't be any different with other comic book heroes.
At this point, I think some sort of clean-up (a soft reboot of sorts, via the timeline alterations of DoFP) is a good idea if they are, at the same time, establishing a clear way forwards.
