I love Juan Piquer-Simón! He's my absolute favorite bad-movie director and, throughout his whole career, he incompetently tried to cash in on simply every successful contemporary trend in the horror and fantasy genres. After the big hit that was "Superman", J.P made his own and hilarious "Supersonic Man", he picked in on the violent slasher-movie madness with the insane "Pieces" and he really over-trumped himself with "The Return of E.T.", the unofficial and downright laughable sequel to Spielberg's SF-blockbuster. "The Rift" is obviously inspired by the series of profitable underwater monster movies like "The Abyss" and "Deepstar Six". From start to finish, you can amuse yourself by spotting all the stolen ideas and shameless rip-offs of these (and other) classics. When a completely new and fancy type of submarine vanishes near the deep Dannekin rift, a second mission with U-boat designer Wick Hayes on board is sent out to investigate what really happened to Siren One. In the dark depths of the ocean, the rescue mission discovers an underwater cavern where the government secretly experiments with mutant sea-creatures. The monsters are quite aggressive but there's also the danger of a government enemy among the crew members... "The Rift" is a forgettable film, but it nevertheless has some ingenious  though very dodgy  monster models. Fans of blood and gore won't complain, neither, as the beastly attacks are quite gruesome and merciless. The acting is very wooden although many of the cast names can definitely do better. It's advisable that you simply enjoy the clichés and gory effects in the "The Rift" because, if you start contemplating about the screenplay, you'll find that it makes absolutely no sense.
