See it if you like hard-hitting writing that is intelligent without feeling high-brow and pretentious.
Don't see it if you are squeamish--if you can't handle Tarantino movies, this isn't for you!
See it if You like thoughtful, dark, dark comedies and don't mind the carnage. Twisty and engaging.
Don't see it if You have trouble with dead bodies, or dead cats for that matter, or are looking for light entertainment. This is not that.
