Domingo de carnaval (1945) could have been much more interesting had it used the full potential of what early 20th-century Madrid during Carnival days has to offer, both in terms of aesthetics and atmosphere. Instead of that, it happens to be a mediocre (and very talkative) whodunit set during Carnival days in Madrid. Main elements include invasive dialogues, lack of tension and a lazy cinematography. Audience's interest in finding who is the real killer unfortunately vanishes after a few minutes. All in all, the sole interest of this film lies in the footages and portrait it paints of the carnival attractions and parades of that time.
