I wanted this movie to be a "so bad it's good" gem very much. The cover looked like a classic 80s cheese-fest that would fill me with much joy and laughter. The opening scene was promising. However, my initial expectations were eventually butchered and thrown into the water like fish bait. The movie gave me little to no reason to invest in the characters. There's almost no backstory for anyone including the lead, David (Treat Williams). What little backstory you get isn't really explored or establishes solid character motivation. Even with the lack of character development, I was at least hoping for some charismatic acting or cheesy dialogue to keep me entertained. Unfortunately, there isn't much of it. The soundtrack was laughably terrible. I'm sure they used the same track of suspense music for every "tense" moment in the movie whether it was a gun fight or a shark attack. It is super irritating after having heard it for the 100th time. It will forever be ingrained in my memory. I wasn't expecting a stellar plot or anything but it was a complete mess. It's like the writer said, "I want to make Diamonds Are Forever," but the director said, "I want to make Jaws." So they compromised and combined them into one movie. As bad as this movie was, there were a few moments that were enjoyable. Almost all of them involved the shark (or sharks? I'm not sure cause they seemed to use footage of multiple species like tigers, lemons, reefs and maybe bull sharks). The attacks were well shot and edited cutting between real and fake sharks. Not saying it was Jaws quality but decent enough for a movie like this. In the end, there really isn't enough "so bad it's good" moments in this movie to recommend it. It's really boring for long stretches and the scenes with the shark are too few and far between to justify wasting 86 minutes of your life (it felt way longer than 86 minutes). FUN FACT: Did you know tiger sharks can roar? I didn't until I watched this movie. Maybe a "nod" to a worse film, Jaws: The Revenge.

David Ziegler (Treat Williams) is an American beach bum living on the Mexican shore with his buddy and business partner Paco (Antonio Fargas). Unfortunately, a lot of melodrama is about to be dumped in Davids' lap because his brother James (Carlo Mucari) got mixed up with a shady businessman, Rosentski (John Steiner), and figured to get rich by secretly recording the phone calls that Rosentski had made to the President of the U.S.! James mails David a CD he's made of these incriminating phone calls. The bad guys recruit Davids' ex-wife Liz (Janet Agren) to try to persuade David to hand over the CD, holding her debts over her head as a means of motivating her. David must ultimately battle the goons that Rosentski sends after him, and *also* do battle with a local one-eyed great white shark (named "Cyclops" by the natives) which has become a kind of personal nemesis for him.Mediocre, fairly dull time waster could possibly have been more entertaining on a "so bad it's good" level, but very crude direction (by Tonino Ricci) and even cruder editing (by Gianfranco Amicucci) prevent the movie from being more fun. That isn't to say that there aren't some very amusing moments here and there, and things do pick up a little during the whole fight / pursuit sequence in the jungle. The music score by Stelvio Cipriani is fun even if it's not one of his best. The use of locations, at the least, is adequate. Williams doesn't look too happy to be here, but Fargas is rather engaging, Swedish beauty Agren offers some appreciable eye candy, and Steiner, the ubiquitous Brit character actor of so many Italian exploitation items, is a passable villain. And as one can see the story is pretty damn silly.By the way, unless the word "shark" is used for its multiple meanings, the viewer should be aware that there's actually only one killer fish in this thing.Five out of 10.

Treat Williams is ineffectual pretty much throughout the film in a flick with little production value or any coherence, plot-wise. The film does however redeem itself with a typical assured John Steiner turn; making the most of a script - what at best can only be described as farcical and even Italian horror muse Janet Agren finds the task of adding some much needed glamour to the film a hopeless impossibility. But before I completely write off this film; hats off to the Tiger Shark's performance - which by the way, stole the show.All in all, a Pulsatingly mediocre film. Good for comedy value.5 stars for the Shark!

-SPOILES- Lame south of the border adventure movie that has something to do with the blackmail of a big cooperate executive Rosenlski the president of Unasco Inc. by on the lamb beachcomber David Ziegler who's living the life of Reilly, or Ziegler, in his beach house in Cancun Mexico.Having this CD, that he gave to his brother James, that has three years of phone conversations between Rosenlski and the President of the United States involved in criminal deals. This CD has given David an edge over the international mobsters who are after him. The fact that James get's a little greedy by trying to shake down Rosenlski for 2 million in diamonds not only cost him his life but put David in danger of losing his as well. Ropsenlski want's to negotiate with David for the CD by getting his ex-wife Liz to talk to him about giving it up, Rosnelski made a deal to pay off her debts if she comes through. David is later killed by Rosenliski's Mexican hit-man Tony, with the help of a great white shark, who just doesn't go for all this peaceful dealings on his boss' part. Tony had taken the CD that Liz left for his boss at a local hotel safe and now want's to murder James, like he did David, and at the same time keep the CD to have something over Rosenlski.David who had secretly hidden the diamonds that James had on him at the time of his murder is now the target of Tony and his men to shut him up for good. David also wants to take the diamonds and at the same time give his boss Rosenlski the impression that the CD that David had is lost but use it later, without Rosenlski knowing who's behind it,to blackmail him. The movie "Night of the Sharks" has a number of shark attacks in it with this huge one-eyed white shark who ends up taking out about a half dozen of the cast members including Tony. David who's a firm believer in gun-control uses knives high explosives and Molotov cocktails, as well as his fists, to take out the entire Tony crew. Even the killer shark is finished off by Tony but with a hunting knife, not a gun. When it came to using firearms to save his friend and sidekick Paco a girlfriend Juanita and his priest Father Mattia lives from Tony and his gang guns were a no-no with David; he was more of a knife and spear man then anything else. The ending of the movie was about as predictable as you can make it with David thought to be killed by the one-eyed shark later pops up out of the crowd,after Rosenlski was convinced that he's dead and leaves the village. David continues his life as a free living and loving beachcomber with no one looking to kill him and about two million dollars richer. to David's credit he had his friend Paco give Rosenski back his CD but under the conditions that if anything happened to him his cousin, who Rosenlski doesn't know who and where he is, will shoot his big mouth off and let the whole world know about his dirty and criminal dealings.
