So bad it’s good? I wouldn’t go that far. But Blood Diner is definitely something—a no-frills pastiche of 1950s disembodied-brain sci-fi potboiler, 1960s Herschell Gordon Lewis splatter movie, 1970s cannibal-cuisine flick, and early-1980s buddy-cop movie. I’m tempted to say it stitches together a Frankenstein’s patchwork of genre movies because it has no vision of its own, but that’s too glib. If nothing else, 20-something Asian-American director Jackie Kong (Night Patrol) loves L.A.: she wrapped all of those genre influences around a love letter to the city’s underground music scene circa 1987, casting punk rockers and rockabilly singers as extras, bit players, and movie stars in a story about a pair of pretty-boy sibling serial killers who run a popular foodie destination on Hollywood Boulevard where the vegetarian dishes are, unbeknownst to patrons, boosted by the presence of human flesh in the recipe.
