Query: Great dark comedy

This is a good example of the potential of dark or black comedy. It's actually funny but also has some really twisted moments. The plot was pretty original too. I love the idea of the employee killing off her bosses. The finale is a bit deus ex machina and the scene itself has almost no lighting, but other than that the film has a good mix of comedy and creepiness throughout.
