Y Tu Mama Tambien raised a few eyebrows with its frank depictions of sex, yet its nonchalant attitude towards intercourse familiarizes us with youthful sex and the lure of promiscuity. Appropriate for a coming of age tale centered on the lives of two 17 year old friends who need nothing else aside from each other and masturbation. The inseparable lives of Tenoch and Julio (or should I say Tenulio) have been interrupted by the whimsical curiosity of Luisa who is married to Tenoch's cousin. After Tenoch's relative cheats on Luisa, she decides to take up the offer of the boys invitation to Heaven's Mouth, a fictional bay made up by Tenoch and Julio. Their road trip is coated with conversations about sex and friendship.
The most interesting and unusual stylistic touch in the film is the use of documentary style commentary on the situations past, present, and future. The sound continuously cuts out to leave room for the "Voice of God" that nurtures and guides the audiences sympathies. It mentions deaths that have already occurred in the past, like that of the roadway accident and also the fate of a fisherman whom the three main characters meet later on. This voice could be connected to the Luis Bunuel's commentary in the documentary Las Hurdes (1933) except Cuaron uses it to allude to past and future plights of the poor of Mexico and the extremely rich society's corruption. The journey that the three take is representative of Mexican third world politics in light of stagnant progressive change. Tenoch, of a wealthy background, treats Julio with pity and disgust in secret, while Julio hangs out with Tenoch for his money and status. They both war over Luisa, a relatively small beneficiary who can offer nothing to the boys but sex and a look at first world politics. The ending especially exemplifies the third world state of a country that can only receive glimpses of first world politics.
Y Tu Mama Tambien is a warming tale of corruption amongst friendship and the details of sexual experience. It will bring you to the brink of friendship and loyalty. Conceptual rules of relationships are bent, broken, and re-shapen in contemporary Mexican society and on the voyage to Heaven's Mouth.
