Mexican film 'Post Tenebras Lux' begins with an amazingly surreal opening sequence.It is a very crucial part of the film as it reveals the ways in which this film's young actors have been directed. Director Carlos Reygadas has not been able to capitalize a lot on the brilliant opening shots as much of the subsequent film is muddled and reeks of pretentiousness.Elements like literature and sex have been introduced by the filmmaker to convey hidden messages. In one instance there are people trying to outsmart each other by sharing their shallow knowledge of Russian literature by quoting some of its greatest authors namely Chekov,Dostoyevsky and Tolstoy. Reygadas also uses sex in order to delve deeper into pretentiousness as names of great philosophers such as Kant and Foucault are taken in order to portray a freaky encounter with strangers in a bathhouse.This film's biggest weakness is its complete absence of a clearly defined storyline which could accompany audiences in a meaningful cinematographic journey.Touted as a family film,'Post Tenebras Lux' gives the impression of merely being a convoluted personal vision of how a rich person behaves in a place surrounded by poor people with problems.The hapless audiences are puzzled as they have the right to know how the film is going to end. Hop la as it comes like a maddening shock.Watch and regret at your own perils.
