Although it started slow, for whatever reason, you could tell from the start that this would be a good one. Very stylish, good direction, it's got the mood of a mystery thriller, and the acting is strong. Mario Casas almost seemed to be putting himself in the persona of his role in the film "Grupo 7" from a few years ago. His role seems very tight, urgent, just like that film. Anyway, this is a very good film. The language seems very clear also for the most part, good film to show to a Spanish class.
