Irreversible (2002)

Gaspar Noe's Masterwork, A Chaotic, provocative and purely brilliant film, containing one of the most uncomfortable scenes I've ever watched.
It's reverse narrative is greatly constructed, and the way the camera just floats around, combined with the editing to create the illusion of the film being one seamless take is wonderful. Though it's not exactly the type of film you'd give multiple views, it is still most certainly a great film.
Side note: This film works great as a double bill with Kikujiro, just make sure you watch Irreversible first.
