Amateurish drek.
That’s the label I was going to apply to Planet of Dinosaurs (1977).
But, after a little wretched setup to explain why this group of people are running around a savage planet, came the dinosaurs. And I had to admit that, for the stop-action era of special effects, they were not at all bad.
So it’s just drek. But I have to admit I laughed when mama dinosaur registered a forceful protest about making her eggs into omelettes. If you’re a fan of movie stop-action dinosaurs, this piece of drek contains some of the best.
