I really should have known better than to go near anything, "anything", with the BBC's name on it but I do like Russell Tovey, so I took a look and quickly regretted it. This thing reeks not only of the usual DEI idiocy I've come to expect from UK but also a certain baseless pomposity, that the UK somehow still means something "prominent" on the world stage. Suffice to say, the hypocritical "touchy feely" identity politics, combined with a dash of UK self importance and a truly irritating soundtrack, quickly got on my nerves. The way Tovey's character seems to spend his time being "minimised", guess no strong male role models, doesn't help either. As for the story, it harks back to 1950's/60's sci fi, about amphibous sea monsters, so even that's not terribly original. Oh but now we have evolved so they are not "sea devils" anymore but instead, hilariously, "Homo Aqua". Yeah, right. I'll try not not laugh too loudly! Limited upside includes decent acting, cinamatography and the creature effects, are, at least interesting. In summary, being lectured by the BBC is frankly absurd. The UK government that pays for them has, figuratively speaking, been in bed with the likes of Israel, so hardly a moral bastion, I would have thought? As for the rest, the story is okay but its so overwritten by brittle finger wagging, that it leaves little to like. A hard pass from me. NOTE: From time to time, not following the "any perspective you like, as long as its ours", DEI bucket, so to speak, can get me trolled (yes people have time to troll on line film/tv reviews, who would have thought!). I guess in its own odd way, it might be said to be an unintentional affirmation, if not a compliment? Suffice to say, I have faith in my reviews and try my best, to be fair, if not necessarily, wholly impartial. Read more
