Visually the movie is fantastic. I got lost in the world of trees, creatures, characters, colors, etc, until the plot started to kick in.
There is plenty of anti-american sentiment here. You can't help but think of our marines beating the less developed people to a pulp while you watch this, or how we're pretty environmentally destructive as a society. I actually didn't have a problem with this though.
My problem comes that the story is a bit childish & simple. I must admit some aspects of it I did enjoy. Seeing a people and planet all connected to each other in a deep way resonated with me.
I've had a tough time rating this. I was so enthralled at some points that I can't rate it low, but I do wish the plot had a bit more bite.
