Strange things are afoot in the depths of the sea. First a passenger plane vanishes over the Pacific Ocean. Then an oil platform is obliterated. Marine biologist Emma MacNeil (Deborah Gibson) is dispatched to investigate the phenomena, and, with the help of Japanese scientist Seiji Shimada (Vic Chao), she makes a discovery that will rock the world: An enormous prehistoric shark and a giant octopus have been awakened from their icy slumbers -- and they're hungry.

Critics Consensus

With shoddy FX, acting and directing. This isn't so bad it's good. It's just so bad it's terrible.

Daft, plain daft. With a few daft but spectacular stunts.

The Times (UK)

This film is bad on every level. In fact, it's bad on levels hitherto unexplored by mainstream cinema.

What a drag. This grabby-titled disaster flick - splashing across the pond on a tidal wave of chuckly publicity - is a damp squib.

Rated: 1/5

Alternate Ending

It's beyond incompetent, and it probably also sounds like it's a hoot and a holler as a result. This is not the case.

If ever there was a film that seemed designed with Mystery Science Theater 3000 in mind, this is it.

I wasn’t going into this movie expecting an life changing experience but I wanted to have so bad it’s good laughs and while they were some moments with the terrible script, flat acting and the usual Asylum awful CGI but the rest was so dull that isn’t worth watching

Rated 1.5 out of 5 stars

The worst acting ever! Overall a terrible movie, and I usually enjoy "bad movies" because they're unintentionally funny. There's a scene where Gibson is piloting a submersible and you see her hands on the joystick. They show a close up of her punching some buttons on the control panel and it's different hands! Her hands on the joystick had plain nails but punching the buttons she had purple nails! No awards for editing!

The CGI is slightly better than anything from the Asylum. Plus, there really isn't anything in the movie that earns the R rating. Not even multiple F bombs. But it is dumb fun. Exciting with a great cast and not horrible CGI. It has a so bad it's good quality. A good choice for a bad movie night.

Rated 3.5 out of 5 stars
