Unfortunately the animation looks like it came right out of a Saturday morning cartoon for 10 years ago. The movements are often stiff, and when people walk they seem to just glide over the background art, traveling either faster or slower than their moving legs would indicate. The character designs are rather lackluster, including the dinosaurs.
I just can't decide who this movie is aimed at. There is way too much blood and gore for children, and the story is so riddled with holes and simplistic that I can't see it holding the attention of mature audiences. With little replay value adults that are interested might want to consider renting it, but this isn't worth the purchase.
