My biggest problem with a lot of these old six-episode serials is a lack of cohesion. The storyline we have at the start is not same storyline we have at the end. It jumps around too much. C. Maybe B.

This isn't as good as that story though. The sea Devils look cool, better than the Silurians, but seem less intelligent than them. The Master is good as ever. Too many episodes, it would of been a stronger 4 parter. Scottybguud View profile Like Liked 0 6 April 2025 · 126 words Review by WhoTheoryYT Spoilers This review contains spoilers! Once again, a very good story. I felt this story was a great continuation of the Master's arc, as well as being a sequel to the Silurians, but above all it felt like a really high budget (comparatively) story with all of the stuff at sea, with a lot of great comedic moments. Some stand outs for me were the Master watching the Clangers, the Doctor playing blindfolded golf to pass some time, and him repeatedly stealing other people's food, all of which combined made this probably the funniest classic story I've seen so far. It feels like Jo is being developed a lot more this series, which I like, and alongside the last serial, this is shaping up to be my favourite season so far.

They go on a little trip to visit the Master in prison. The three of them talk for a little bit, everyone is very polite. And Jo Grant, who has been mind controlled and almost killed by the Master several times, smiles at him and waves goodbye when they leave, completely unironically. This girl has my entire heart. Someone please get her a sandwich, the Doctor ate all of hers :( The whole plot is pretty good, the Sea Devils look amazing, all the side characters/villains are great, specially Capt. Hart and Blythe, the clever secretary. The pacing is also great, which is a must for a 6-parter. You can really tell the BBC was giddy with how much stuff the Navy was letting them use for this story: so many guns and boats of all types. The Master and the Doctor on little jet skiis. Jo Grant driving a motorcycle and that huge floater boat thing. 10/10. The fencing fight is incredibly silly and instantly iconic. Jon Pertwee is chewing that sandwich as fast as he possible can to be on time for the cue for his next line. Amazing. mndy View profile Like Liked 1 22 November 2024 · 8 words Review by Rock_Angel 1 Jon Pertwee era stop being boring challenge impossible Rock_Angel View profile Like Liked 1 Show All Reviews (8) Open in new window Statistics AVG.
