Okay, let me state why he WOULDN"T be a good Wolverine (considering I am a huge fan of Wolvie):
1. He does not have the look of Wolverine. His face looks nothing like him and he doesn't really have a Wolverine physique. I mean, Wolverine is short and stocky, but he is also ripped.
2. He can't act... Why would anyone wanna watch a movie with a main character who ruins the movie because he can't memorize his lines.
3. Hugh Jackman is already Wolverine in the movies. And he did an excellent job.
