Sayng almost anything about "Buey" ('Ox' in English) would greatly reduce its impact. Completely watchable, the film is shot almost entirely in close-up with matchingly intense soundtrack. It's engrossing from start to finish, and open-ended in the sense that the meaning of the plot is open to interpretation, though every viewer will be certain that he has the 'real' meaning. The movie is literally a tour de force and not to be missed.
