YMMV / When Dinosaurs Roamed America

  • Most Annoying Sound: Most of the dinosaur noises may be seen as such, thanks to how awfully mechanical and synthesized they sound.
  • Nightmare Fuel: All of the large theropods, except for Nothronychus.
    • The Dilophosaurus roar is one of the most memorable things about the show. Though for some, it's actually a Most Wonderful Sound.
  • Special Effect Failure: Quite a number:
    • When the Rutiodon lunges out of the water, its tail goes above the surface, but there aren't any splashes or ripples.
    • As the "Syntarsus" pack prowls the forest, one shot has them walking in air.
    • The Dilophosaurus eating the Anchisaurus corpse is actually the reversed footage of it killing the animal, thus the Anchi's head rises up into the mouth of the predator by itself.
    • As a young Triceratops playfully rolls through the vegetation, its neck-frill passes into the ground.
  • What An Idiot: The raptors in the fourth segment die in a forest fire because they were too busy eating to run away.
