This is a "last tango" which has made its mark as a distinctive film work. What transcends from the screen to your hearts and minds is as eye opening as anything you'll ever see, and as effecting, if not more, as your own personal life experience. One can only hope more interesting things coming from this director and Mexico's gain is our loss, as it's obvious Mr. While they were one "Charolastras" the name for their tightly knit group of friends , they are now sworn enemies who resent one another. Sexuality takes many different forms and has many different effects throughout the film. The road liberates them, erotically, philosophically, for better and for worse. It's the lives few of us will ever live, for better or worse.

In the beginning, we see that sex is a major preoccupation for the two friends, as they have sex with their girlfriends, masturbate beside one another at the pool, and comment on the attractiveness of their respective penises. The woman's bare breasts are seen briefly as the man suckles on them. Likewise, Luisa's motivation seems more despair- than romance-driven. She is alternately joyous and inconsolable about her lot. The dialogue is fresh and funny, the kind you just know cannot be faked, that in fact somewhere somehow the writer or actors uttered those phrases.
