El secreto del arrecife

I found this on Tubi and watched it over the course of a week because I'd always put it right before bed and usually fall asleep a few minutes into it. I was expecting a talk fest with little action, but once I watched the whole thing, I found a pretty decent low-budget movie. The acting is serviceable, the plot is alright, and there's plenty of action and decent practical special effects. Worth a watch for fans of science fiction B-Movies.

R. Lee Ermey is the only reason to watch this soggy underwater submarine sci-fi film. He has a starring role, and his presence for the mercifully short 79 minute running time helps maintain some interest. "Endless Descent" is loaded with the usual crisis of the minute clichés, and races along with little character development, and really makes little sense. The crew explores an underwater cave system, while being attacked by a nice assortment of evolutionary accelerated critters. Meanwhile a toxic plant specimen is overrunning the submarine. Throw in a traitor on board, and you pretty much have the plot, or lack thereof. Except for the presence of R. Lee Ermey, this is entirely forgettable nonsense. - MERK

Saw this as a kid 20 years later still like it. Not likely you will find this but if you do watch it. I've seen a 100 low budget flicks like this it is in the top few percentile. Has a weird cool 80s/90s movie feel mullets and all! Also full of above average gory special fx. If you like Carnosaur, critters or Leviathan you gotta see this.

Endless Descent (aka The Rift) is the afterbirth of 1989's underwater explosion of The Abyss, Leviathan, and Deepstar Six. Just as you expect from an apparent bandwagon jumper, it's not as good as those prior flicks. It also takes some time to get going. It has the feel of Voyage to the Bottom of the Sea for the most part of the film (and the sub effects are just as hokey). It doesn't turn into a true B monster movie until they finally get out of the damned submarine. Then we get some giant killer seaweed, rubber mutants, and a nice head explosion. I might add that the head explosion was the highlight of the movie. Jack Scalia leads a cast of mostly unknowns and no one here shines. Even R. Lee Ermey and my man Ray Wise seem to be phoning it in. The director's other films include the horrible Pieces and the unwatchable Cthulhu Mansion. So viewer beware.

This film sucks on every level. Directing sucks, story sucks, actors suck, creatures suck, sets suck. It's just awful across the board. I didn't realize this film even existed and was the third underwater/monster movie of 1989 (Leviathan and Deep star 6 being the other two). The other two movies mentioned are like Citizen Kane compared to this one. Watch those two for a cheesy, but somewhat fun underwater monster movie. Dont watch this one...you'll never get that hour and half back in your life. It was free for me on Amazon, and i still want my money back.
