"Like the film's characters, we find ourselves party to scenarios involving the most extraordinary fetishisation of suffering and death, horrors which invoke a troubling combination of impressions: they are sensual, grotesque, dreamlike, oddly beautiful, almost pornographic, usually painful to witness. But however horrifying the experience, Tras el cristal is bound to make for rewarding viewing. It is profoundly disturbing, potently evocative and easily one of the most lyrical nightmares ever concocted." - Chris Gallant, Kino Eye
