It takes only one example to demonstrate how laughably bad this movie is. The movie ends with one of the female killers beating some poor 1/2 way handcuffed sap to death with a shovel. The big twist is before he dies he clicks the empty end of the handcuff to her ankle. The movie ends with their skeletons handcuffed together. Simple question: why didn't she use the shovel to chop off his dead hand and just walk away? Beyond stupid.
