This movie is the proof that the world is becoming a sick and dumb place

Sadly Over-hyped

An action-packed slog

Exactly the movie you think it is, but not the movie you want it to be.

When all four of the two engines fail on a jet there's big problems. The tombstone toothed pilot and his incomprehensible Jamaican co-pilot request advice from their air command, which has the threatening codename "grandmother". Grandmother orders them to drop their nuclear bomb into the sea creating a large explosion of stock footage. As any scientist will tell you this can only mean one thing - a giant monster on the rampage around the coast of Spain. This is all done in code so it sounds like "Grandmother here, calling baby, drop the bottle in the sea and return to auntie via brother-in-law". Apparently the Russians have cracked their code but I doubt anyone in the audience could. You get the jist of it though, big explosion and big funny looking monster biting the top off lighthouses and generally being a danger to shipping.A sea captain who is constantly being asked if he's drunk and some woman set out to prove it's real, which is tricky because it's clearly a big glove puppet. My favourite scene was the courtroom case involving a 25ft fishing boat where even the clerk of the court was an admiral.Funny from the first line onwards with masterful dubbing I give it 19/10 with a bonus point for every exploding rowboat taking it up to a respectable 30/10. The ending is especially good, take that Africa - one giant monster coming your way! Not our problem any more.

"Hydra – The Sea Serpent" is fantastic and downright brilliant entertainment. That is to say; at least if you're into stupid, cheesy, trashy, tacky and totally incompetent euro-Exploitation material. From the creator of some really great and highly respected European horror landmarks, such as "Tombs of the Blind Dead" and "The Lorelei's Grasp", comes this must-be-seen-to-be-believed piece of 80's incompetence that you simply cannot bring yourself to hate. The film begins with a really cheesy sequence of a military airplane, code name "baby", in contact with the radio base, code name "mother", and receiving the order to drop a nuclear bomb, code name "baby's bottle", in the Atlantic Ocean. The explosion instantly causes a regular-sized sea serpent, as the only living thing in the entire ocean, to mutate into a giant and radioactive monster. And yes, all this even happen before the opening credits! Even after the exhilarating opening sequence, the monster doesn't waste any time and promptly devours half the crew of a Spanish fisherman's boat and a female American tourist who thought it was a brilliant idea to go swimming in an unlit and unguarded area whilst completely drunk. Of all stupid people I ever watched dying in horror films, she deserved it the most! Her traumatized friend teams up with banished fisherman Pedro, but obviously nobody believes in the existence of a massive sea creature and they call in the help of the eminent professor Timothy Wallace; who actually should have been retired for at least two decades already. "Hydra – The Sea Serpent" is indescribably entertaining for all the wrong reasons. Whenever the film attempts to be spectacular and terrifying, you'll find yourself practically laughing your lungs out. The monster is an adorably ridiculous sock-puppet who likes to twist itself around cardboard lighthouses and swallows entire mannequin dolls without even chewing. At a certain point in the film, the critter even manages to grab a helicopter out of the sky and munch it. Also, pay attention to the catchy but nevertheless knocked-off Jaws music whenever the monster threatens to pop its head out of the water. Okay, the film is too long in parts, especially since Amando De Ossorio insisted to provide the obligatory "let's-fall-in-love" montage and several more completely irrelevant sub plots, but overall "Hydra – The Sea Serpent" is the type of garbage I instantly fall in love with.

This film has me seriously doubting again whether Armando de Ossorio was a good filmmaker or not... His BLIND DEAD films are praised by many fans. This I can understand. But wanna-be Gothic vampire trite like MALENKA doesn't show any signs from a gifted filmmaker. And that also goes for SERPIENTE DE MAR. It features horrible acting, a dumb plot, stupid events, a lot of other things you can expect from a bad monster-movie and also veteran actor Ray Milland, who does his best to mumble his way through this film while not having much of a clue about what he's doing in it. Apparently Milland was already very ill while shooting SERPIENTE DE MAR (his last theatrical feature) and going out with a ridiculous stinker like this, makes it all the more sad. One last appearance alongside Peter Cushing in a made-for-TV film directed by Roy Ward Baker (also in 1984) doesn't change much about it.But the sock puppet/sea serpent is a hoot to behold. Watch it swirl up a lighthouse and crush it. See it destroy a harbour with miniature boats. Look at it demolish bridges and munch on charming miniature trains.Good Badness? Yes. 3/10 and 7/10

I have a VHS copy of this lame film subtitled in Portuguese. It has some truly laughable scenes with a giant a sea Serpent engulfing a whole woman in the Tamariz beach at night...On the underwater sequences the "monster" looks like a muppet!... A MUST SEE!!!
