Open Water

"Kentis ends up treading water until, finally, the whole film gets sucked under."

"Simply a stunt - hopelessly literal-minded and cheap in every sense."

"Clearly, this one will divide viewers, but the vote here is that Open Water is an unpleasant experience."

"A taut, 79-minute fright fest peppered with enough payoffs and glossed with a mournful philosophic overlay."

"You can feel the water, stretching against an unsheltering sky, seep into your bones."

"Ultimately too under-dramatised to provoke anything more intense than squirming discomfort."

"On a visceral level it's about as much fun as watching someone pull the wings off a butterfly."

"By no means a good movie."

"A tiny movie about ocean fears that will flush that overrated The Blair Witch Project 20,000 leagues under the sea."

"It'll leave you with the creeps and make you think twice about swimming in the ocean..."

"It gets under your defenses and sidesteps the 'it's only a movie' reflex and creates a visceral feeling that might as well be real."

"Wrings every possible drop of tension out of a simple premise and a micro budget."

"It's ridiculously cheap and terrifying at the same time."

"You can almost taste the saltwater, and the fear."

"Kentis keeps it simple and direct, and the effect is devastating."

"It's a very pure, basic kind of terror, nail-bitingly fun to watch; made more so by the startling realism of the sharks."

"An ingenious triumph of imagination over budget."

"As the clock ticks on, the sharks thresh and the dialogue continues to stagnate, you might just catch yourself wickedly thinking: Come on sharks, let's do this."

"We, the audience, shuffle out of the theater, feeling drained and punished."

"Becomes a slow and steady descent into pure fear."

"The unforgiving power of nature (is) on display to amazing, and frightening, effect."

"Terrifying precisely because it doesn't go in for cheesy shock tactics and special effects."

"It's a triumph of chills on the cheap that delivers its gut punch of terror by slowly but surely immersing distinctly everyday characters into the unthinkable."

"As it dawns on the couple that they've slipped several links down the food chain, you're right there with them."

"An unjustly forgotten shark movie of the highest, nerve-shredding calibre."
