Mammoth pyramids

Caught the movie 10,000 BC last night. Here's an excerpt of the review at IO9:

In 10,000 BC, you've got Egyptian pyramids being built by guys using woolly mammoths. I mean, it's the goddamn ice age, and then our main character walks over a hill and suddenly he's in the Nile Valley of 2,000 BC? And these anachronistic bad guy Egyptians (from the ice age) have got ships, horseback riding, and freakin STEEL. Steel? C'mon, guys, you couldn't even consult Wikipedia? I mean, why not just call the movie 2,000 BC and make it about ancient Egypt? Or keep it in 10,000 BC and come up with some other kind of bad guys? Jeezus.

I enjoyed it.
