This movie flat out sucked for me. However, I guess that it could be entertaining for the child's eye. Nic Cage's voice was not fitting for an enormous caveman and it was even slightly creepy. Bottom line, if you're going to watch this movie don't.
This is a quality film. I find it a bit slow moving at times but the dialogue is absolutely flawless. I highly recommend watching it in 3D as that just adds another layer of awesomeness. It is a great movie, but it is not as entertaining as I hoped.
