I had only seen this movie once prior to tonight, which was in December 2011 or so if I can remember correctly. Either way, the last time I saw it I only half watched it, my excuse is that I was around 15 and nowhere near as interested in films as I am now.
So it's fair to say that my memory of this film, and the 4 stars I previously rated it based on that first viewing, were both flawed.
It's redundantly a 5 star film.
P.S. Although, a case could be made that the worst parts of the film, the Esmeralda Villa Lobos scene and each second of the film between Butch and his French girlfriend, are bad enough to drag this down to 4 and a half stars. But I'm feeling generous and the rest of the movie is so good for those flaws to be insignificant.
