This film is a jewel among modern Mexican films, it has one of the best scripts I have ever seen, it delves into the why of things that happen. The performances are very good, the car chase sequences are good, most of the action sequences are also good but others are not so good, it is fun, the only bad thing could be that some scenes are filmed in the "Azteca Stadium" but they do not add anything to the story to record them in that place, it is a bit unnecessary to have used that location, but despite that it is entertaining and highly recommended.
