And so, naturally, the sushi chef slasher movie would be called: Slashimi. And so these drunk, obnoxious, spoiled, bigoted college students would always go to the same sushi joint to eat dinner after a night of partying, and they'd be so hammered that they'd act all offensive all the time, making a stereotype Japanese voice to order their food with, insulting the chef again and again, referencing Godzilla constantly, calling each other "round-eye", and doing every annoying, asinine, racist, etc., thing imaginable to the chef again and again, night after night, until finally he snaps and goes on a well-deserved rampage against these jerks. (Slasher movies are always the best when the victims are all completely insufferable jerks so we can root for the killer.) And so he'd stalk and kill them all one-by-one, and cut them up and prepare them like giant ngirizushi and temaki, wrapping them in nori, rolling them in sesame seeds, smearing them with wasabi, mixing a sauce of blood and ponzu, etc. And of course, they'd all be there, prepared as giant dishes, at the restaurant the following evening and enjoyed by all, who have no idea what they are, but everyone just assumes they're some new sort of style containing the much sought-after toro (fatty tuna).
And if this movie's a hit, then it will be time for the sequel, with the further adventures of the Sushi Slasher: Slashimi 2: A La Carte, and: Slashimi 3: All U Can Eat.
And if anyone complained of these movies being in bad taste, the filmmakers can simply claim that these movies are trying to scare people away from sushi due to the unsustainable overfishing of the oceans to meet the demand for sushi, and as such these are environmentalist/conservationist message movies aimed at waking people up to serious issues of the day, wrapped in a popular movie genre that shocks viewers into awareness, and hopefully horrifies and traumatizes them away from wanting to eat sushi anymore. And, honestly, this would fit right in with the shock strategy used by extant anti-meat groups like PeTA, who rely on shock value for maximum resonance in order to communicate their message within a low budget.* (And if people don't respond to the didactic intent of the films, a new sushi slasher movie series could have a plot whereby ocean conservationists feel the world is so threatened by the overfishing of the oceans due to sushi consumption that they dress as sushi chefs and become slasher killer avengers intent on both scaring people away from eating sushi and also punishing habitual sushi eaters and aficionados.)
* BTW: When you think about it, The Texas Chain Saw Massacre movies, and the entire inbred backwoods cannibal genre (like Wrong Turn, etc.), are exactly the kind of shock horror message movie that would work so well for anti-meat groups, because when you think about what these movies are doing, it becomes clear that the plot mechanism not only produces terror and horror, but it also puts human characters in the same position animals slaughtered for food are in on a daily basis, and it would only take a knowing line of dialog to make sure the viewers make that connection, and then perhaps think of that and feel sorry for the animals the next time they think of having meat to eat.
