I'm sorry, but I just had to link this (requires Shockwave):
It's so awful I laughed the entire time it was playing. I've been considering showing this movie to my kids, but I hazard a guess they'll understand it no better than I did the first few times I saw it. (In fact, I almost hate to admit that I didn't understand it until I saw a 2001 parody backed by 2010...what did apes beating up each other with bones have to do with spaceships to the moon? Doh! So, tell me again, exactly who's evolved?)
Nah, the kids won't get it, and probably wouldn't enjoy it. Not enough weaponry. Best to stick to Transformers. They are part of the iPod generation, after all.
