Yeah, I kinda felt that the X-Men could've brought in some way better mutants. Honestly Kitty was there for pure comedy, "DONT YOU KNOW WHO I AM!! I'm THE JUGGERNAUT witch." Why didnt they bring Kurt Wagner? Or ever Jubilee could have done a better job than Kitty.

Also, Magneto didnt really want to kill the X-Men, and he didnt know that they were going to resist until they did. And even then, he still doesnt want to kill a fellow mutant.

And dude, MAGNETO IS ALIVE AND WELL!!! Im sooooo happy ROOM FOR AN X4!!
