My husband was watching this and I tried to. The plot sounded interesting, but too many "little" things that left me shaking my head. As several other reviewers have pointed out, the costumes were unbelievable, the people were too clean to have been pre historic. Why didn't the whole tribe go on the hunt? A teenage boy at that time would have been a man with a mate and would have known how to do everything the other men knew. Where did they get those round, painted rocks to put on the grave. I sure didn't see any laying around on the prairie. It looked like winter with snow during a lot of the movie, so where did the flies come from? I'm glad I was home and could entertain myself with games on my iPad and read the reviews.
