Summary: Good Visual Effects Movie
Review: Leviathan unlike the Abyss was one of numerous underwater thrillers that had good special effects but needed more work on the script. Peter Weller played a good part but should've stuck to playing Robocop and Richard Crenna who played Doc has never been the same since First Blood in 1982. But all in all A great film.

Summary: Come on people, this movie was not that bad
Review: Listen, I am not saying this movie was on the level of alien, but let's get real. It was as bad as a Carrot Top movie. Well acted and some good special effects make this a very entertaining movie. Give this movie a chance and I can guarantee that you will be surprised. Enjoy!

Summary: what is this . . no nudity??
Review: The only thing that saved Lifeforce and Species from being complete crap is the fact that we get to see two babes nude. Nothing like that here so I'll say bye-bye to this film . . avoid!!!

Summary: Simply a soggy piece of cheese.
Review: There is very little good to offer in Leviathan, Jerry Goldsmith contributes the usual excellent score, but that is about it - despite being trapped with a monster, which is a pretty unispired (and hardly seen) guy in a suit, the story never really catches fire. If you are like me and enjoy watching laughably silly cinematic misfires like this, then by all means check it out. If not, and you've seen both Alien and John Carpenter's The Thing, then skip it, you won't miss it at all.

Summary: Sad
Review: This is a poor man's ALIEN that takes place underwater. It's pretty sad. The only thing that saves this bomb is the cast, which is actually good. But everything else is pathetic. It's a totally uninspired, forgettable, ALIEN-clone, with nothing interesting at all. I was even bored with the action (if you want to call it that) at the end.This movie has been totally forgotten, and rightly so. Most people have no idea what this is. Don't waste your time with this one. Why deal with the imitations? Settle for the real thing. Watch ALIEN.

Summary: Doesn't live up to its ambitions
Review: This is a special effects movie from 1989. Considering its age, the special effects hold up very well. However that can not be said about the plot of this movie. There first half of the movie starts slowly and it attempts to build supsense until the monster arives. Unfortunately the monster itself is so preposterous that its arrival only brings a major let down in the plot. The extended chase sequence is straight out of 'Alien' but holds none of the emotional tension that 'Alien' succeeds in providing. This is a movie that tried to replicate the success of 'Alien'. It is really just 'Alien' placed underwater with none of its suspense.

Summary: Better than alien!!!!
Review: This underwater version of alien is very exciting even if the script is not spectacular. The plot is good and the creature effects by Stan Winston are marvellous. The unbelievable music of Jerry Goldsmith help a lot.

Summary: Alien meets Abyss meets crap
Review: To my surprise I actually enjoyed the first half of this movie. But once this poorly made fish creature began appearing while devoring half the cast, the movie transformed into an exact clone of Alien and I lost interest. Peter Weller and Ernie Hudson are the bright spots in an otherwise routine monster film with an unbelievably stupid ending.

Summary: Leviathan's a shipwreck
Review: What happens when you mix one hundred percent 'Alien' with fifty percent 'The Thing' add a dash of 'The Abyss' and add no originality of your own? Voila! You get Leviathan. This montage (montage is putting it very, very nicely) of 'Alien', 'The Thing', and 'The Abyss' doesn't even try to hide the fact that it is a rip-off of all three sci-fi classics. Instead, Leviathan unabashedly tries to make money, almost scene for scene, off retred ideas and comes up flat. Not even the all-star cast (how did the producers get Peter Weller and Richard Crenna to sign their names to this?) and an ineffectual Jerry Goldsmith score can save this shipwreck.

Summary: I can't believe anyone liked this...
Review: With all of the bad qualities of Alien and none of the good...another crap film wasting the interesting possibilities of human mutation (does anyone actually READ good science fiction anymore?) A typically claustrophobic underwater film which despite some interesting set design is essentially a one set film (which I hate)... Forget it. If you must see claustrophobic underwater films, see Das Boot or Abyss!
