Well, I can only say the filmmakers tried, at least that's something... And I might also be rather too generous in my rating. But "Deep Shock" is at least worth a little bit more than its poor 1.9/10 IMDb rating (at the time I first saw it; apparently I was right, since it went up to 2.5/10 by now). The film is somewhat of a cross between "The Abyss" (1989) and maybe "Deepstar Six" (1989) and a zillion other "in the deep blue ocean" horror/sci-fi flickies. Juiced up with a lot of questionable CGI and a lame 'ex-wife/ex-husband get back together in the end' subplot. It gets a little credit for the background story that was given to the creatures and how they came to exist. But that's about it, really.
