Re: First Class 3 or X-Men 5?
I would agree that at this point in time, the First Class versions of Beast and Mystique are going to be more relevant than the main trilogy versions.
For one, Mystique was cured and Beast left the X-Men. For 2, they were most recently portrayed by Lawrence and Hoult, and it could be argued that Beast was more relevant / developed than Grammar's version.
