David Slade is a genius. I can't remember the last young director to so amazingly execute a film. The shots, the editing, the acting, are all pitch perfect. It's really a masterpiece. The only strike against it is the subject matter, which is a turn off for a lot of people. But, that being said, it's so expertly done, so well-crafted, that it doesn't matter what it's about. It's a movie about 2 people who are pathological liars embroiled in a battle of wits, the equal to which we haven't seen in a LONG time. This is classic cinema, and we're going to see a lot more of Slade in the future, if there's any justice in the world.
