Many of my friends laugh at me when I mention this movie. I don't know what makes so many of them hate it so.. Perhaps the lack of understandable dialogue? Too much like thinking to understand what is going on? Whatever it is, I am one of the few I know who feel this is a very underrated movie.. I know it is not accurate from a scientific perspective... The time line is all messed up.. but so what? I sat there in the theater just thinking.. "suppose live in our distant past WAS something like this movie. Fire=Life=Fire. Along comes a superior tribe and I realize that I could summon the flames at MY WILL. How powerful I would feel.. Almost G-d like! The photography is lush and there is a tinge of humor when the backward tribe learns to laugh. I enjoyed the story and the acting... everything. Rent it! See it twice if you must. Just maybe... we ARE looking back at ourselves.
