Splatter is often the sad step-child of horror. When done correctly, or within context, it’s beloved if bloody. Very bloody. It can even be used to bring a bit of humor into your otherwise aggressive arterial spray (isn’t that right, Sam Raimi and Lloyd Kaufman?). Septic Man falls into the former category, taking a surprisingly serious tone over something that should be salacious and scatological.
Indeed, the movie revolves around a sanitation worker who gets trapped in a toxic underground sewer and suddenly transforms into a hideous combination of feces and filth. There’s also a subtext of possible pandemic, maybe-imaginary creatures, good vs. evil, hero vs. villain, and perhaps the most idealized view of virulence ever put on film.
