Other reviewers have outlined the story quite well so I'll keep this short. This film is very entertaining and very funny. Of course that depends on what you find funny. Almost all the humour is so called black comedy. Some people might find the comedic scenes distasteful but they made me laugh out loud and that's because, although gory, they are somewhat cartoonish. The script is tight and flows nicely although the film could have been 15 - 20 minutes longer. The ending feels a little rushed and is not as satisfying as it could have been. These are small quibbles and overall I would heartily recommend the film both for the thriller and comedic aspects.
