contemplativeFirst off, I just want to say that despite the silliness of the plot and the total irrelevance of the dinosaurs to the story itself, I rather enjoyed this episode in a vicarious kind of way. As noted, the dinosaurs were irrelevant to the plot (other than Solomon's desire to capture them, and the whole business with killing the triceraptops to make a point), but they were fun to watch, although the first couple of them were a bit grotty. The ankylosaurs didn't come off all that well in the episode's first couple of bits with dinosaurs, and then came the sleeping juvenile tyrannosaur early on in the show. It appeared to be a bit...tubular, without shoulders to speak of. Not good, not good at all. The remainder of the dinosaurs seemed to work well, and looked good except the raptors, which didn't have feathers, but that's another matter. However, all that said, the dinosaurs in "Dinosaurs on a Spaceship" certainly were much better than those in the Pertwee tale "Invasion of the Dinosaurs". Worst. Dinosaurs. Ever.
I also thought it was odd when the Doctor commented, "I've never had a gang before.", as this is certainly not true in New Who as witness the "gang" in "Demon Run", the gaggle of folks that joined him in the Tennant Davros storyline, and the UNIT days. Among others.
Other than that, not much else to say about the episode. 'Nuff said.
