At 18, fresh from high school, Marina, Ignacio, Adam and Mimi, school mates bonded by fate, shared a dream about adult life, a dream of fame, success, perfect skin and that one endless, true love that, surely, was waiting just around the corner for each one of them. But 30's arrived, and none of the sweet promises of youth was fulfilled. Alone, failed and frustrated, all four are forced to stop and look around to try to understand where it all went wrong, and find an emergency fix for their lives, before it's too late, and happiness escapes through their fingers forever. Secondary Effects is the bitter coming of age comedy that follows their steps in the search for lost dreams, lost hair and good sex, at least, if true love turns out to be a mirage.

Kind of hits the target
30 September 2006 | by danixdefcon5See all my reviews

Well, maybe it is because I am actually near the intended target age group (those nearing 30, and I'm 25). Its got an interesting philosophy, it actually fits better than other recent Mexican movies, which seem to have matured from the god-awful "charro" movies from the 50's or the "Lola la Trailera" low-budget action flicks from the 70's and 80's.

It is mostly a comedy about 4 (well, 4 main, and some secondary characters) that re-unite 12 years later in a high-school reunion. They're about to hit 30, and well the movie tackles on some of the issues related to hitting 30, specially with some of them not having their teenager dreams fulfilled.

During the whole film, and in the closing dialogue, this movie also shows one thing: everything we do has Side Effects, which might be good or bad.
