2. A Full X-Men vs Brotherhood Battle
Even though there have been three X-Men films with the X-Men fighting the Brotherhood, we are yet to see a full blown X-Men vs Brotherhood battle. The first X-Men film did have some fights between individual X-men and members of the Brotherhood. Due to the constraints of the battlefield (and no doubt budget restrictions), we did not see all of the X-Men fighting all of the Brotherhood at the same time. The second X-Men film had the X-Men and the Brotherhood working together for most of the film. X-Men: The Last Stand finally presented an opportunity to show a full X-Men vs Brotherhood battle. When the film got to the climax, there were only 2 members of the core Brotherhood, and they took turns fighting. X-Men: First Class gave us something close to a full-on battle, but with relatively unknown villains. Days of Future Past presents an opportunity to have a full X-Men vs Brotherhood battle, with all of the X-Men and Brotherhood fighting at the same time. It will be exciting to see a youthful Magneto with Mystique and Emma Frost fighting an all new X-men.
