7. Retconning The X-Men Franchise - X-Men: Days Of Future Past
Time travel can be both a blessing and a curse, but given that a) this movie was being adapted from a beloved comic book story and b) it gave director Bryan Singer a chance to fix everything he didn't like about the previous X-Men movies, it was most certainly a blessing. For starters, the movie abandons Professor Xavier's death in X-Men: The Last Stand from the outset, refusing to explain how he came back to life and just asking audiences to go with it. However, the most prominent changes come once Wolverine has convinced past Mystique (Jennifer Lawrence) not to kill Bolivar Trask (Peter Dinklage) at the end of the movie, preventing the green-lighting of the Sentinel program and essentially pressing the reset button on all of the X-Men movies to date. Wolverine wakes up, and though he's still fallen in with Professor Xavier and his crew, most of the events of the previous movies simply haven't happened. Most importantly, we see that Jean Grey and Cyclops are still alive, and as such, The Last Stand can simply be a distant memory. Did It Work? Emphatically yes. While we're not at all clear on what exactly has and hasn't happened in the new timeline, Singer came up with an artful and intelligent way to fix those plot elements from The Last Stand that fans totally hated. Now we can put The Last Stand and Origins: Wolverine out of our minds and look forward to what the franchise has to offer us next...
