Deep Blue Sea [Blu-Ray]

On the Blu-Ray commentary track and special feature "When Sharks Attack," Renny Harlin and many cast members discuss the plausibility of the science behind Deep Blue Sea, citing their lack of disease and deterioration as believable reasons that sharks may hold the cure Alzheimer's, cancer and so on. Now, I'm not sure if any of them watched the movie, or read the script, but it's about genetically engineered giant smart sharks that herd people like cattle, take out cameras, play dead and manoeuvre with ease around the corridors and rooms of a small human living quarters after they fill with water. Plausibility should be the least of their concerns. Trying to justify any of this with any sort of high-minded rationale is absurd, especially when the entire ordeal is really just a tongue-in-cheek, referential ordeal, with nods to Harlin's previous works (Cliffhanger and Die Hard 2) and all things James Cameron ― even down to the unnecessary underwear scene where Saffron Burrows electrocutes a shark. As a parable of what happens when science defies God, the single-minded scientist (Burrows), the preacher cook (LL Cool J) and the heroic man of the sea (Thomas Jane) run around an Aliens-like compound while everyone gets picked off in traditionally unpredictable ways for the genre. Think of it as a Judeo-Christian Scream, but with an enormous budget and killer sharks. There's nothing believable, artistic or even particularly dignified about it, which is just par for the course with anything related to Renny Harlin, no matter how hard he tried with Cleaner. But this isn't necessarily a bad thing, as he does have a knack for creating a propulsive commercial narrative, often being as good as the script he's given to work with; he just has absolutely nothing to say beyond demonstrating technical acuity.
