The tricky thing with good movies set in historical or prehistorical settings is that often we have less than we'd like to go on and must rely on artistic interpretations for dramatic or practical effect. Bad movies like this just don't care. I have little regard for productions that insult a well informed audience by carelessly throwing in obvious impossibilities, hoping that no one would notice. I go to a theater or sit down at home to be immersed for a hour or two in make believe that ought at least to be *believable*. So when I see the heroes interacting with animals or beasts that have no business being where they are through plot arcs that flaunt mainstream scholarship on the subject, it takes me out of the fantasy and makes me wish I'd chosen something else. This movie is so inaccurate with regards to ice age natural history and what we know about early humans through archaeology, a documentary to explain all of them out would take as long as the running time of this one. After the disappointment of 2008's 10,000 BC, my expectations were low going in. yup. Not much better.
