This is an odd little movie. Although the animation and layout of the film might make you think that this is going to be a straight-up documentary like the BBC's "Walking With..." series, "Dinotasia" is more like a series of vignettes surrounding the experiences of a few individual dinosaurs (a pterosaur learning to fly, a tyrannosaurus couple defending their territory, etc.). Although Werner Herzog is cast as the narrator, he barely speaks at all, though he usually introduces each vignette with a few short lines, but these are more related to the theme of the narrative rather than scientific facts.
Although it comes off a bit cartoonish at times and might turn off people who came in expecting a true documentary, "Dinotasia" is quite an enjoyable viewing experience. At the very least, it's the world's first and only black comedy that can boast photo-realistic animated dinosaurs!
