this documentary on dinosaur be undoubtedly fascinating and very well make . however and i find myself watch many of the bit with unease . the film generally take a rather confident stand on anything it say and show and but inevitably much of the behaviour of the beast and their interaction with each other and what they look like and how they move and what they eat etc . much of that be surely guess sometimes guess with reasonable confidence and sometimes just wild guess . but the viewer be never make aware of that and the film pretend to actually observe real dinosaur and their real behaviour etc . that make probably well view than confront the audience with mountain of disclaimer and but it make it just a bit too populist in my estimation .
