I enjoyed Valhalla Rising a lot. It's a very divided movie, half of people who see it just hate it.
The whole idea of being in the old world and going to new continent for the first time is exciting. Even at the end when he see's the natives who kill him, seeing someone of a difference race would have been like seeing an alien.
I'm not really sure if Valhalla Rising was meant to be a kind of **** you to Christianity since Madds played a human form of Odin more or less. A lot of euro pagans very much still see Christianity as the enemy.
