I don't really buy the introvert thing. The guy is obviously an adrenaline junkie, and I haven't come across to many introverts who were adrenaline junkies. The guys obviously got a past to make him the way he is, but it's never even hinted at as to what it might be. An older character it would be easier to buy into because of a person's life experiences, but when a relative kid acts that way, it just strikes me as not enough hugs from mommy and daddy as a child. And his "cool" bordered on comatose in some scenes. I actually liked it when he was roused, 'cause he actually showed some depth. The McQeens, Eastwoods and Marvins carry off the acting on body language and through their eyes alone. Gosling isn't there yet, imo. He may get there, but not yet, and I'm not alone in that assessment. This is the first Gosling movie I've seen, so I'm not tainted by character expectations. It might be a case of right actor, wrong time. Again, good movie just not the masterpiece a lot of people make it out to be, imo.
