This independent movie directed by Karyn Kusama is a fabulous piece of movie making. It is a diabolical plot which shifts swiftly from one perspective to the other. The perspective of the protagonist who goes by the name Will and played by the actor Logan Marshall-Green is where the heart of the plot lies. You believe his mind and where the audience will like to stay in because of the intrigue and the pain he seems to go through. If he represents one group to identify with then the other two are the people that send the invite and the rest of the friends. All the characters are fleshed out well which only a well written script can achieve.
I am tempted to write about the ending but then a film that happens in one night will always have a dramatic ending. Yes, The ending is great and so is the entire film. Fantastically directed and ably acted. It is must see in a quiet ambience on a lazy but calm evening.
Will, the main character will remain with you for a long time to come.
