These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel / Squick: Dinosaurs eating meat in gory detail, and some of the experiments also qualify.
The Triceratops killing the T-rex, we see the inside of the T-rex when it's getting punctured by the Triceratops' horn.
They Just Didn't Care: The "Triceratops crash test". The scientists drive a replica of a Triceratops skull into a porous aluminum wall (representing T. rex), and when the skull breaks to pieces, they conclude that the animal was just as vulnerable. Two things wrong with the experiment: both of the participants. A real-life Triceratops head would naturally have all sorts of strengthening tissue supporting the skull, and T. rex... clearly wasn't a large, square-shaped metal surface.
Visual Effects of Awesome: The program had some spectacular effects for a TV Documentary, especially the parts when the presenter walked around and interacted with the dinosaurs. That said, the CGI model for the Tyrannosaurus skeleton looked quite bad.
