Deep Blue Sea was never exactly supposed to be high-quality entertainment, given the project's schlocky B-movie premise about hyper-intelligent sharks chowing down on a bunch of archetypal character actors. It may be regarded as one of the best 'sharks eating people' movies ever made, but aside from Jaws there isn't really much in the way of strong competition in that category.
What it does have going for it is the one scene that almost everybody thinks of the moment they hear the title Deep Blue Sea, namely Samuel L Motherf**in' Jackson's now-legendary monologue. A classic 'rally the troops' speech found in so many 90s' studio pictures, Jackson gives an impassioned plea to his fellow survivors only to be cut short when a hungry super-shark snatches him out of nowhere and drags him to his doom in a cacophony of agonized screams and crap special effects.
Whether director Renny Harlin intended his movie to come across as quite so brazenly ridiculous is anyone's guess, but there's no denying that the cheesy genre flick would be lost to history were in not for this one unforgettable scene.
