I thought everybody these days knew that prehistoric humans didn't live with dinosaurs. Not that I'm opposed to human vs dinosaur movies, but I would prefer they take place in a setting explicitly defined as fantasy (as is the case with movies containing dragons, elves, and orcs) as opposed to passing them off as depictions of our actual past (especially if they provide a specific date like 10,000 BCE).
Hehe. Watch the trailer. It's inaccurate, but not as bad as you're thinking....
