Epic, is not quite an appropriate word to describe this film, although it has an "epic" quality to it because of the historic events it borders to.
I would rather like to describe it as "amazing" and "fantastic". :-)
I liked it a lot because of the time they took to communicate emotion, they really managed to develop the characters. I loved the amazing rainforest environment and the action. There was two or three instances of gore which they could have spared us, but other than that - fantastic!
