There’s no pretense about Dinosaurs on a Spaceship. It is exactly what it says it is and intends precious little more. This isn’t a bad thing necessarily.
The Unicorn and the Wasp was such a story as was Delta and the Bannermen from the classic series. The problem with Dinosaurs is that there was so little setup before charging headlong into the story that there was little investment in character, even Rory’s father.
In a sense this story served the same purpose as The End of the World, an apt demonstration of what the a modern series of Doctor Who can look like (which unfortunately makes Pertwee’s Invasion of the Dinosaurs look even shabbier for all the wrong reasons). Certainly for the second straight week the visuals were outstanding, and the mention of the Silurians was a nice, and logical touch.
But the predicates for the Ponds leaving are being laid subtlety. Next week it’s a trip back to the old west for our high plains drifters.
