My favorite film of the 00's. More so than Mulholland Drive, Zodiac or Cuaron's own Children of Men. Just a perfect masterpiece that touches on so many things, but, to name a few, it's about matured and burgeoning sexuality, dealing with mortality and your own transience, living in the moment, growing up, growing apart, Mexico, love, and, perhaps most importantly, the many facets life can take, from the personal to the political to the sexual. The fact that I'm still deciphering what it all means is simply a testament to how good this film is.
Also, did I mention that it's so damn hot? Like the sex scenes in this completely put English-language cinema to shame (with the exception of maybe David Cronenberg movies). Hollywood take note. More sex pleeeeease.
