Synopsis

Researchers on the undersea lab Aquatica have genetically altered the brains of captive sharks to develop a cure for Alzheimer's disease. But there's an unexpected side effect: the sharks got smarter, faster, and more dangerous. After a big storm damages their remote research facility, they must fight for their lives.

    75 Gleefully yet seriously stupid. It cares about every moment of its absurdity. Deep Blue Sea offers a great underwater facility setting, a productive use of space and camera movement in conjunction with incredible animatronics and hilarious CGI, and strong stock characters who are easy to root for and observe in their bloody demise. Quality B-shelf action/horror hybrids like this are hardly made anymore, replaced by ironic z-grade DTV trash, so appreciate films like Deep Blue Sea as the treasure that they are.

    Kind of the only movie to ever exist that depicts sharks as Sam Fisher from Splinter Cell while also being overt Christian propaganda. Incredible, the 90s were a wild time. Podcast- Deep Blue Sea

    Deep Blue Sea is a mess, but a deeply entertaining one (if you pardon my stupid pun) Because it’s a mess and because I’m lazy and tired, I’ll just provide some thoughts and notes, instead of a proper review: * First of all, Saffron Burrows. She’s pretty and all that, but what a black hole of charisma she is in this movie. I don’t think she emoted at all, even when she was in danger. I know, that she was supposed to be the cold, rational scientist, but she acted like she was the coldest cyborg ever built. Her dramatic performance is on par with Ashton Kutcher in The Butterfly Effect (this is not an compliment, as anyone can imagine).…

    Little known fact: this was the motion picture that finally spurred the Hollywood Foreign Press Association to create the Golden Globe Award for Best Use of Stellan Skarsgård as an Underwater Projectile. It was also, unsurprisingly, the award’s first winner.

    Deep Blue Sea is a fun creature-feature film that does not take itself very seriously and maintains a decent pace thoughout. The story is mostly predictable but it did have a few subversions of common tropes that I was pleasantly surprised by. The set and cast is good and elevates this title over a lot of similar productions, even if the CGI is very dated by today’s standards.

    My only major gripe is that the main characters remained very one-dimensional. This generally wouldn’t be too bad for a film like this, but the dialogue constantly hinted at backstories that were never explored in-depth or even lead anywhere, so it was a bit of a missed opportunity. The final conclusion still managed to be satisfying though.

    It’s definitely worth a watch if you just want to turn off your brain and watch people get chased by mutated sharks in a ridiculous and over-the-top manner.

    The science behind this may well be plausible – that cures for human ailments may well rest elsewhere in the animal kingdom. To that end Saffron Burrows (“Susan”) enlists the help of millionaire philanthropist “Russell Franklin” (Samuel L. Jackson) to develop a cure for Alzheimer’s using sharks captive in a converted offshore submarine refuelling base. When he arrives at the facility he meets the rather oddball crew including “Carter” (Thomas Jane”) “Preacher” (LL Cool J) and “Jim” (Stellan Skarsgård) before quickly discovering that these genetically altered fish are tired of being the guinea-pigs in the lab and are bent on revenge. The film does not hang about; the effects are quite scary at times but the one great snag is given that the sharks are supposed to be super-intelligent: why did they agree to star in a film with the dreadfully flat Burrows – there are bits of flotsam in this film less wooden than her performance. Jane & LL Cool J have some fun as they try to evade their menacing foes and though it certainly isn’t “Jaws”; it’s not terrible…

    **Peak corny shark goodness!** 🦈🦈🦈

    Deep Blue Sea falls prey to every shark movie trope and has a blast doing it. Embracing its cheesiness makes this movie one is the all-time best shark flicks—a fabulous cocktail of 90s cheese, sharks, and surprising twists. If you haven’t seen this one, I guarantee you will be surprised by who survives and who doesn’t.

    An engaging thriller with a mindless plot, Deep Blue Sea managed to keep me hooked throughout its loud 100-minute running time. A doctor and her team of researchers looking to find a cure for Alzheimer’s in sharks in an isolated facility in the middle of an ocean – what more do you need for some sweet chaos while also supported by some unethical practices? Deep Blue Sea is not the most realistic shark film out there but it has a lot of cool action, suspense, the added pleasure of flooding sequences, and a protagonist that you love to hate. Go for it. (Grade B-). TN.

    Great watch, would watch again, and do recommend.

    This is probably my favorite shark movie. I know “Jaws” did a thing back when, but I like this better. It doesn’t mean it’s a better movie, the same way that more people like pizza than salad even though salad is a better food.

    The biggest part of why I like it so much better is that it’s a survivalist situation, in an isolationist setting, and the sharks are “intelligent” so they’re actively hunting the humans so it becomes a killer creature feature too.

    The cast is really good, and you should probably recognize about half the faces, whether or not they’ve been in Marvel movies.

    The split story lines bother me a bit, and more when they’re voluntary, but it works. And when someone gets eaten by a shark, everyone else greedily makes an opportunity of it in a good survivor’s fashion.

    This is a movie fueled by adversity instead of stupidity, as is a soft requirement for some movies. I guess the “stupidity” is creating the situation in the first place

    If you like sharks eating people, or underwater bases (“Rapture”), or liked “The Meg” then give this a watch.

    There’s quite a cast assembled for _Deep Blue Sea_, not what we’ve come to expect from the Asuylum-soiled genre of shark movies in this day and age. It’s not a fantastic movie, but it proves more watchable that 90% of its company.

    _Final rating:★★½ – Had a lot that appealed to me, didn’t quite work as a whole_.
