Why would anyone compare a Judd Apatow comedy to an erotic drama like Y Tu Mama Tambien? They don't even have that many similar thematic elements. Funny story, in the "Superbad" track commentary this review is brought up by Jonah Hill. He comments on how ridiculous the review is and how "not cool" it is to compare "Superbad" with "Y Tu Mama Tambien."
"The friendship of Seth and Evan has homoerotic undertones, and there's a funny scene where they declare their undying love for each other. But because this is an American movie, don't expect the frankness of Alfonso Cuaron's "Y Tu Mama Tambien," which took the close friendship of two horny teenage pals to its logical conclusion. In "Superbad," the lovefest between the best friends is strictly platonic, which makes it nonthreatening to the crowds at the multiplex."
