Agreed. The first two X-Men films toned down certain character's powers, and it seemed like he was afraid to let certain characters loose at many points. This is one area I felt X3 was stronger. Storm, Magneto, Iceman, Pyro, etc. were allowed more freedom in their powers use. I'd like to see someone whom embraces the the mutant powers and embraces the out there elements of the X-Men world more. You can't do certain X-Men stories without certain elements being embraced, which is a big reason the Phoenix has never worked without the Shiar and such on film or in the Ultimate world.
Meld storytelling ability and action/powers skills, and we'll get X-Men films that make Singer's films not look as good anymore. Doing away with FOX would help, but not gonna happen anytime soon
