Deep Blue Sea/YMMV

Crowning Moment of Awesome: "You ate my bird."
Ear Worm: "Deepest! Bluest! My hat is like a shark's fin!"
Ensemble Darkhorse: LL Cool J's character Preacher spends most of the movie alone, separated from the main cast, who never even seem to remember he's there (probably because he was assumed dead). He's definitely the most popular character in the movie with most audiences.
Executive Meddling: Makes for a damn fine climax.
- Originally, Dr Susan was to survive and Preacher would be sharked. Test audiences found Susan to be such a irritating twerp that this was inverted.
Hilarious in Hindsight: Sorta. The special effects company involved with making the animatronic sharks would create the shark animatronics (some of them even look identical) in Shark Night nearly twelve years later.
Nightmare Fuel: Most of the shark kills, but one in particular: half of a guy is eaten... and then the foot twitches.
- How about the lead scientist who was strapped to the gurney and used as a Battering Ram to break the observation window? Made ten times worse by the fact that that he was not only still alive because of his oxygen mask, but awake. *shudders*
  - Amazingly, the scene manages to wring a bit more horror out of it by having him still alive and conscious while his gurney's stuck in the window, watching his screaming and sobbing wife have to be dragged out of the room and leave him to die.
Special Effects Failure: Renny Harlin challenged audiences to notice when the mechanical sharks ended and the CGI ones began. Form a line, folks...
Took the Bad Film Seriously: Everyone but Saffron Burrows looks like they're about to burst laughing.
Unfortunate Implications: The film's trailer made the choice to set Susan's Fan Service scene against Scoggins' line "She screwed with the sharks, and now the sharks, they're screwing with us."
