well rhodey was pretty much underused in this film and so was stane so....
At least magneto had purpose and a great actual idea to make the mutant movement important by making important people mutants. He also showed the 'do as i say, not as i do' atitude by not willingly wanting to kill himself for the cause and rather the life of rogue. Great dialogue between xavier and magneto as well and it also had the best balance of having wolverine being central because it was roughly surrounding him (unlike the other two films which had no right to be wolvie centric).
I'm not doubting it had its flaws but as a script, I believe its the strongest of all superhero movies even though it's actually the most original. I can almost forgive it considering it occurred so long ago.
I just remember that cage fight scene from wolverine, no scene in a superhero film has had that sort of impact showcasing a character for the first time, not even nightcrawlers ass whooping or blade in the club in the first film. It's the only time ive been convinced the comics had come to life.
