Here's
another review.
"In a nutshell: Dumb prehistoric quest adventure with lots of CGI mammoths and nary an original thought in its Cro-Magnon head."
Glenn Whipp had
a review as well, and it includes the Ten Commandments of Prehistoric Movies.
The History Channel ran a show last light,
Journey to 10,000 BC, but as usual they got
everything wrong. No one attacked a prehistoric civilization, no one formed alliances with mammoths and sabre-toothed cats, and there wasn't even
one pyramid!
