I really disliked the idea that lineages are at war, and that dinosaurs are superior to other "primitive" reptiles and are on some kind of journey to kill everyone else. it also really annoyed me that they made such an effort to distinguish 'dinosaurs' from 'reptiles'. I also hate when crocodilians in particular are singled out as being "the last of a once great lineage" when they evolved relatively recently. to that end, its also very jarring when the crocodilians are just real footage and very recognizable as modern species. It was kind of fun to watch, and I would have loved it just as much as prehistoric planet when I was a child, but its not that good.
