I wasn't sure if he was good for the role or not, but then I actually watched Breaking Bad and realized that this guy could nail the role! I won't go into one of my close examinations with this though, you should all know if you've watched the show and read the books... b1tches.
I loved Breaking Bad and in particular Aaron Paul's character. When I think of the film version of Eddie Dean however, I think of Ryan Reynolds. Not so much for his look but the smart ass way he delivers his lines. 90% of what came out of Eddie's mouth was dripping with sarcasm and I see the same thing from everything Ryan Reynolds has been in. See Blade Trinity for example.
