Director Bryan Singer uses the idea of time travel to link all the X Men, & Wolverine movies together in order to start anew.

My memory is a little foggy so I will have to re-watch the original X-Men trilogy in order to see any changes or errors in the X-Men universe from Days of Future Past.

My only real disappointment in the film is that of the remaining mutant survivors. I know the mutants are being hunted down but Storm outliving Juggernaut or Havoc, had me scratching my head in disbelief.

All in all a very satisfying movie.
