Captain Hart issues a command, which puts The Doctor, and his efforts for peace, in grave danger.
I really enjoyed it, it's a classic story, but I'm going to have to start by saying, we've been here before, it is very much The Silurians Mark II, there are multiple similarities, not just the foe, but the plot and characters, The Doctor is attempting to broker peace between the humans and a range of ancient reptile beings, he goes in good faith to negotiate, only this time he has Captain Hart in his way, as opposed to The Brigadier.
Nevertheless, it is a very, very good story, I think The Sea Devils look wonderful, the production values are terrific.
Edwin Richfield is marvellous as Captain Hart, and yes we've seen this type of character during the Pertwee run before, but he's very well drawn, pompous, single minded, and obsessed with food.
It's incredibly well made, the production values are better than episodes made well into the future. Pertwee as always is terrific.
Very good, 8/10.
