Something extraordinary weird happened in 1989: a staggering five production companies released an underwater scifi movie back to back. The best known out of these five is naturally The Abyss, while the fate of the four others remains to be always compared to the James Cameron’s masterpiece.
Lords of the Deep does unfortunately not fare well in the comparison with any of its competitors, ending up the weakest one of the bunch by margin. The movie reminds more of a low budget TV series (think underwater Star Trek), but despite the shortcomings of the set design and costumes the movie manages to sell the idea of an underwater base – if only barely. The same does not apply for alien lifeform, and it would require quite a bit more imagination than what I have to buy the silly storyline.
As with Star Trek, there’s something strangely endearing about the clumsiness and silly costumes though, and in an alternate universe Lords of the Deep might’ve had a somewhat potent one or two season TV series in it.
