Starting with the leading performance from the first diva in Mexican cinematography according to some (Andrea Palma), without forgetting Domingo Soler who also makes a great contribution to the cast in this film, then the great strength of the plot and the masterful direction by Arcady Boytler. All in all this movie cannot be considered less than excellent. So yes, maybe some of the scenes don't result quite the way they should, but most of them do. Particularly the scene from the carnival at the beginning of the movie and the last scene bring you to the verge of tears. Yes it also many elements of a catholic moral (Rosario lives in guilt, her way of paying her sins is by means of sacrifice),  but we have to consider the movie was released in 1934 and the Mexican society of the time had those values dictating our lives and, weather we take this into consideration or not, I think the the plot is really really tough and the theme very strong. Maybe nowadays we have many movies with plots that are twice or thrice as tough, but I think this is still a great, great movie and has no soap opera can never even remotely compare with it. Also, it is one of the first movies with recorded sound in the Mexican film industry.Starting with the leading performance from the first diva in Mexican cinematography according to som
