Re: X-Men 4: Age of Apocalypse
I think an age of apocalypse movie would feel too much like a rehash of DoFP. It also wouldn't be wise to use Apocalypse for the first time in AoA. It would need to be explained how this character we've never seen before would have taken over North American in the absence of Xavier.
I would much rather the series end with an adaption of Fatal Attractions or X-cutioner's song.
