1989 saw three "Alien under the sea" horror/sci-fi pictures of which Leviathan was, by far, the worst (the other two were big budget The Abyss and B-movie Deepstar Six).
This bargain bucket thriller utilises the exact same plot as Ridley Scott's 1979 classic, with inferior performances, tacky creature design, rubbish visual effects and cheap, predictable death scenes. Deepstar Six was marginally better, and that's saying something.
