For most other directors this would easily be a career high-point, but such is the consistent quality of the Coen brothers' filmography that Blood Simple has been undeservedly under-appreciated by many. This is a taut, taciturn, tense and twisty thriller, despite (or maybe because of) its ultra-low budget. It's undoubtedly rough around the edges, but that cinematic grit is part of the charm, and complements the violent, unsettling tone of the movie well. And every element of the brothers' craft (dialogue, cinematography, editing, sound, music) is precise, and in perfect harmony with each other. As a piece of independent, genre filmmaking, Blood Simple is endlessly impressive.
The hallmarks of their sensibility are evident here from the start - the humour/horror blend of Fargo; the sparse, natural soundscape of No Country for Old Men; the noir pastiche of Miller's Crossing/The Big Lebowski, etc; the pitiable, amusing stupidity of the selfish/money-chasing characters of well, everything they've subsequently made. The environment is unmistakably Coen too, and not just the barren landscape of 80s Texas (i.e No Country). Many of their films seem to centre around creepy, dangerous motels and hotels, and that's very apparent here.
The characters are thinly developed, but that's intentional. Everyone in the story is unknowable, always plotting a plan, or an escape. The actors bring them to life very naturally. Character actor legend M. Emmet Walsh is a standout, as the eccentric, probably psychotic private detective. And Frances McDormand, in her debut role, conveys a lot despite doing, and saying, very little.
The film's atmosphere is eerie but irresistible, and there are a couple of set pieces (always involving bodies and blood) that genuinely mesmerise. The finale, which is funny and disturbing in equal measure, leaves you pondering some surprising questions as the credits roll; questions about the plot, yes (how? what? why?), but more interestingly, questions about real things, like fate and the future, morality and mortality.
That a 90 minute exploitation movie could provoke and impress so much is an inarguable testament to the Coens' talent. Watching Blood Simple, it's clear they always had it.
