I can't believe how unheard of this film is, further to that - I hope this is ordered in soon, this is one of the greatest American works of all time.

If you think that films like Pulp Fiction are the be all and end all of movies, you're in for a surprise. While the characters have a superficial similarity to Tarantino's characters and also play with our expectations she isn't doing it to bowl us over or shock us, but is merely a side affect of the insight the film has and what it reveals about us. In a nutshell this film is about life and isn't just like a comic book.
