Badass Decay: The old Edmontosaurus. Justified, and started prior to the events of the show because of a brain tumor. It goes From Bad to Worse for him.
Narm: The Albertosaurus pack attacking the Edmontosaurus herd is legitimately terrifying, but one scene reaches absurdity when one of the albertosaurs actually jumps a long distance to attack it's prey. Large animals simply cannot make long and high lunges and the Albertosaurus is no exception. The rest of the scene is still scary though.
Nightmare Fuel: There's one scene where the Edmontosaurus are ambushed by the albertosaurs where one literally leaps (like a raptor) out of nowhere to tackle one of the poor plant-eaters. Imagine three tons of teeth and death leaping at you. Not to mention that the filmmakers use slow motion to chilling effect in some of these scenes.
Nightmare Retardant: The appearance of the feathered tyrannosaurs can come across this way to some viewers, which isn't helped by the ridiculous Contrived Stupidity they often fall prey to in the program.
