The co-writer on the Thor movie has this to say about the intent of the film:
"You want to feel Thor's rage when he rages. You want to see him fight like hell, and take as much he dishes out -- maybe more. You want to have a visceral reaction to the guy, and what happens to him. You don't want his adventures to be clean and antiseptic. You want to see the dirt, and grime and blood. You want to feel every bone crunching moment of every fight. And when he unleashes the storm, you want to feel like you're seeing the power of a GOD at work ... But at the end of the day, he's a man. In the comics, Odin sends him to Earth because he's not perfect. He's brash, arrogant. Even over-confident. We all know that guy -- some of us have even been that guy. Stan Lee's genius was to give Thor-as-hero an emotional throughline we could all relate to, and knock him down a couple of pegs. So on that level, your question answers itself. The challenge is to dramatize that and make the audience see what the fans have known and believed about the character all along."Read more at Cinematical.
