History YMMV / DeepBlueSea

* AlternateCharacterInterpretation: While Susan gets most of the blame for genetically modifying the sharks, Whitlock was also involved, and she never outright says that it was her idea. Whitlock's AGodIAm attitude towards their work doesn't exactly rule out the idea that he may have been behind the enhancements.

* SignatureScene: [[spoiler: [[SurprisinglySuddenDeath Samuel L. Jackson getting munched by the shark mid-]]RousingSpeech.]]

-->'''[[spoiler:Shark]]''': (as it [[spoiler:eats Russel while interrupting his RousingSpeech]]) [[Film/PulpFiction Oh, I'm sorry, did I break your concentration?]]

* TheScrappy: Susan, while having some defenders who see her as a flawed but sympathetic heroine, is widely and vehemently despised by much of the fandom for a variety of reasons: the fact that the entire mess is her fault, her continued justifications, generally unpleasant nature, and Creator/SaffronBurrows' DullSurprise performance, unintentionally making the character come off like TheSociopath. Test audiences infamously ''hated'' her so much they were shouting "Die bitch!" during the screenings. [[spoiler:The studio went back and reshot the ending [[TakeThatScrappy just to kill her off]].]]

** Music/LLCoolJ's character Preacher spends most of the movie alone, separated from the main cast, who never even seem to remember he's there. This makes one wonder if he was even originally intended to be in the movie, but eventually he turns out to be a lot more intelligent and even more likable than the other characters. Apparently he was popular enough that the movie was rewritten to give him a bigger role in the climax.

** Most fans prefer the theatrical ending, where Susan, the scientist who creates the sharks for Alzheimer's research, [[spoiler: is dramatically killed while using herself as bait]]. There are a handful of fans, however, that would have preferred to at least 'see' the alternate ending where [[spoiler:she survives]].

** Despite being TheChick and having less screen time than almost everyone else, Janice is fairly well-liked. Her sunny and skillful delivery of the film's exposition and her role as the only one of the three scientists who respects the laws against genetic engineering both make her endearing.

* HilariousInHindsight: Sorta. The special effects company involved with making the animatronic sharks would create the shark animatronics (some of them even look identical) in ''Film/SharkNight'' nearly twelve years later.

* SugarWiki/AwesomeMusic: "[[https://www.youtube.com/watch?v=B-a6UJMYTEU&feature=player_embedded Deepest! Bluest! My hat is like a shark's fin!]]"

* AlternateCharacterInterpretation: While Susan gets most of the blame for genetically modifying the sharks, Whitlock was also involved, and she never outright says that it was her idea. Whitlock's haughty attitude towards their work doesn't exactly rule out the idea that he may have been behind the enhancements.

* TakeThatScrappy: [[spoiler:Susan's death is very much this, seeing as it came about after test audiences shouted "die bitch!" during the original cut where she survived]].
* TheScrappy: Susan, while having some defenders who see her as a flawed but sympathetic heroine, is widely and vehemently despised by much of the fandom for a variety of reasons: the fact that the entire mess is her fault, her continued justifications, generally unpleasant nature, and Creator/SaffronBurrows' DullSurprise performance, infamously making the character come off like TheSociopath. Test audiences infamously ''hated'' her so much they were shouting "Die bitch!" during the screenings. [[spoiler:The studio went back and reshot the ending [[TakeThatScrappy just to kill her off]].]]

* CriticalResearchFailure: The film makes a big deal about how unusual it is that the mutant sharks would eat the Tiger shark. This ignores that cannibalism is very normal for sharks, and it wasn't even the same breed as the mutated ones.

** Most fans prefer the theatrical ending (hell, it was reshot at the request of the test audiences), where Susan, the scientist who creates the sharks for Alzheimer's research, [[spoiler: is dramatically killed while using herself as bait]]. There are a handful of fans, however, that would have preferred to at least 'see' the alternate ending where [[spoiler:she survives]].

* JerkassWoobie: Susan has watched Alzheimer's ravage her father, is forced to destroy the medical research she's devoted her life to, and has a couple of extremely terrifying run-ins with the sharks, [[spoiler: the last of which she doesn't escape.]] However, her blatant disregard for basic safety protocols and ethical experimentation (directly leading to the rampage), lack of remorse, and generally unpleasant nature still leave her as a fairly difficult-to-like-character.

* TheScrappy: Susan, while having a ''small'' number of defenders seeing her as a flawed but sympathetic heroine, is overwhelmingly despised for a variety of reasons: the fact that the entire mess is her fault, her continued justifications, generally unpleasant nature, and Creator/SaffronBurrows' DullSurprise performance, infamously making the character come off like TheSociopath. Test audiences infamously ''hated'' her so much they were shouting "Die bitch!" during the screenings. [[spoiler:The studio went back and reshot the ending [[TakeThatScrappy just to kill her off]].]]

* RetroactiveRecognition: The team include [[Film/ThePunisher2004 The Punisher]], [[Series/AgentsOfSHIELD Victoria Hand]], [[Franchise/MarvelUniverse Nick Fury and Dr. Selvig]].

* UnintentionallySympathetic: An interesting example. While originally intended to be a sympathetic character, poor fan reaction to Susan led to modified AllForNothing ending, clearly looking unfavorably on Susan for the rather reckless and illegal methods she chose in order to cure Alzheimer's Disease. While most viewers agree with the message (see: her Scrappy status), a small segment hold this view, nothing just how devastating Alzheimer's is, how many people's lives it damages, and believing that the risks and ethically questionable decisions Susan made were absolutely worth the risk.

* AlasPoorScrappy: [[spoiler: Susan realises her attempts to cure Alzheimer's were AllForNothing and she pulls a HeroicSacrifice to ensure the death of the last shark]].

* BaseBreakingCharacter: '''Susan!''' For a very long time, she was listed as TheScrappy on this page due to being primarily responsible for the sharks' rampage and hesitantly trying to justify the first few deaths as worth the risk. Test audiences hated her so much they shouted "Die, bitch!" during the screenings [[spoiler: and the studio changed the ending to accommodate them.]] However, over the years, many fans have come to sympathize with Susan due to her sympathetic motive of finding a cure for Alzheimer's (and her story about what the disease did to her father), her competence against the second shark, and how she is put through a lot by having to strip down while fighting the second shark and losing [[spoiler: the research she'd worked so hard for.]] Most, although not all, of the people in the second camp wish that [[spoiler: Susan had lived, and hope that a future home media release will include the alternate ending where she ''does'' live.]]

** Most fans still enjoy the theatrical ending, where Susan, the scientist who creates the sharks for Alzheimer's research, [[spoiler:is dramatically killed while using herself as bait]]. However, there is a steadily growing minority that feels that an alternate ending where [[spoiler:she survives]] should have been used instead of [[MultipleEndings or along with]] the theatrical one. One factor bending this is the lack of real-world progress in treating Alzheimers since the film's release, loaning more sympathy to both Susan's motives and [[spoiler:fans' desires to see a character who could potentially cure the disease survive.]]

* JerkassWoobie: Susan has watched Alzheimer's ravage her father, is forced to destroy the medical research she's devoted her life to, and has a couple of extremely terrifying run-ins with the sharks, [[spoiler: the last of which she doesn't escape.]] However, she loses some sympathy for disregarding safety protocols while experimenting on the sharks (making her partially responsible for their rampage) and taking a while to show remorse.

* TakeThatScrappy: [[spoiler:Susan's death was intended to be this after test audiences shouted "die bitch!" during the original cut where she survived]].
* TookTheBadFilmSeriously: A review of the film said that it works because everyone [[HamAndCheese isn't taking it seriously]], making it quite fun. The exception is Creator/SaffronBurrows, who "behaves as it was an art film" (and unlike most of the examples of the trope, not everyone enjoys it).
* UnintentionallySympathetic: The AllForNothing ending was clearly intended to show how 'bad' Susan was for daring to successfully engineer a way to cure Alzheimer's Disease. What is really galling is that Susan is 100% correct - they could wipe out degenerative brain disease with this research. Alzheimer's is ultimately fatal, and affects an estimated 5million people ''in the US alone''. But no, apparently we should cheer [[spoiler:the death of the scientist that would have saved MILLIONS.]]

** ''Deep Blue Sea'' provides a less universal example than most but still has some passionate advocates. Most fans still enjoy the theatrical ending, where Susan, the scientist who creates the sharks for Alzheimer's research, [[spoiler:is dramatically killed while using herself as bait]].

* TookTheBadFilmSeriously: A review of the film said that it works because everyone [[HamAndCheese isn't taking it seriously]], making it quite fun. The exception is Creator/SaffronBurrows, who "behaves as it was an art film" (and unlike most of the examples here, with mixed results).
