The War Between the Land and the Sea: The Witch of the Waterfall

 "You'll never swim alone!"

Hmm. I can see what they're trying to do, and even admire it. There's a racism and xenophobia subtext in this episode, especially given that the phrase "great replacement theory" gets bandied around at one point. Far right conspiracies, rich oligarchs, populism... these are, of course, terrible things. So Salt gets arrested, there's the deepfake image of her claiming responsibility, all so very topical. It's all very well done, but perhaps a little too obviously on the nose.

Then there's the weird romance between Salt and Barclay, now rebels together against both human and Sea Devil. Yes, we've seen their mutual attraction, but I'm not sure I buy this. Again, we have the racism angle, and this is supposed to show an interracial relationship as a contrast to all the MAGA-type racism. But the analogy doesn't hold. Barclay and salt aren't people of different ethnicities, they're literally a mammal and a reptile... "interracial" is a much bigger deal here.

And there's Kate, overworking and ploughing through her grief. Jemma Redgrave is superb here, but the character just isn't that deep, and this deep focus on her characterisation just doesn't really work as a consequence. And the stuff with the conspiracy, and the stressed prime minister in over his head... again, I like and appreciate what they're trying to do in theory. But the execution makes no sense. Why is a British PM being advised by American and French generals rather than the Cabinet? Why is an American general giving orders to the British army on London's streets? The whole thing doesn't quite come off, and I just don't buy the stand-off at the end.

Perhaps I'm being a little harsh. The whole thing looks superb, and the performances remain first rate. The dialogue is often impressive. But I'm not sure this is quite working in terms of the execution when it comes to both plot and subtext. I hope the finale makes me feel differently...
