Sinornithosaurus is described as having a venomous bite. Yet this theory had been refuted years before this show was made.
The narration says that Gigantoraptor may have been the largest feathered animal ever. However Therizinosaurus, which is suspected to have had feathers, is much bigger.
The CGI feathered dinosaurs have their primary feathers attached to their third finger, even though fossils plainly show they were actually attached to their second (or middle) finger.
