My kids enjoyed watching this. The graphics are great, and I don't mind the fictional liberties taken to make the history more interesting- otherwise my kids probably wouldn't watch it. What I do mind is the narrator saying "your ancestor..." in reference to a fish getting it's first backbone.
This is a movie which, be forewarned, takes party with the rest of the 'intellectual' morons who treat Darwin's Theory of Evolution as fact; when in reality it is just that: a theory. A theory which will one day go down as the biggest practical joke in academia history. Anyway, check it out. Decide for yourself.
