Blood Simple.

"But what I know about is Texas...And down here, you're on your own."

What jumped out the most to me about Blood Simple was its suspense and unpredictability. The most unpredictable moment for me takes place after Ray finds Marty shot at his bar, and tries to cover up the murder, thinking that Abby committed it. Ray throws Marty's body in the backseat of his car, and drives away to dispose of it. During this drive, Ray hears the sound of heavy breathing and realizes that Marty is still alive. After bolting from the car out of fright, Ray sees Marty crawling down the road with his last breath. Ray gets into his car, and throws it into drive. He decides to not run over Marty, and gets out of the car to grab a shovel out of his trunk. Ray walks over to Marty, and raises the shovel above him. He holds it there for a long moment, but decides not to bring it down on Marty when he sees a truck approaching from the opposite side of the road. Ray drags Marty back toward his car, but doesn't leave him in the path of the oncoming truck, as I thought he might. We then see Ray digging a grave in a nearby field. Ray throws Marty in the hole, and proceeds to kill him in an even more brutal way than any of the other opportunities he had before: by burying Marty alive.
