This story was pretty good. The actual story was very nice, if a bit badly paced. That being said, I think it could've used a bit more explaining. Most of the cliffhangers are just the Doctor facing a dinosaur, but overall, I quite enjoyed them, for reasons I'll get into later. Pertwee, Sladen, and Courtney are on point here, as is the rest of the UNIT crew. I enjoyed how they got the feeling of not knowing who was on the Doctor's side, and that twist would've surprised me, if I had no prior knowledge of this story. I enjoyed the settings, and the Dinosaurs. Dear Lord, the Dinosaurs. They. Were. Terrible. I love them all with my whole heart. Overall, a very great story to put on that's hard to fault.
