Re: Which characters from X3 and Origins would you want to remove
Yes they could have been easily utilized if only the writers didn't add so many characters that Juggernaut, Phoenix, Deadpool, Gambit and Angel ended up doing less.
And I would have kept Callisto because she had a purpose in the film, if it wasn't for her mutant abilities, like sensing mutant powers, Magneto wouldn't have known that Jean Grey is alive and more powerful than ever. Also, Magneto probably wouldn't have tracked down Mystique. Plus those 1-on-1 fight scenes with Storm!
