Re: What didn't you like about the film?
Most of my dislikes faded away when i saw it for a second time. The fights seemed very fast-cut, that was about it as far as thinking things could have been done differently.
Seeing it for a second time made a huge difference.
Get rid of J-Law's Mystique, bring back Emma Frost and Banshee - and properly develop Storm, Psylocke, Angel and Jubilee. Stop butchering the source material!
