The movie is the story of Michelangelo Merisi da Caravaggio who was an Italian painter in the 16th century, through the eyes of the Pope's investigator. He was known for painting "what he saw", some kind of reality that he wanted close to the divine, which was of course not ok with the Catholic Church. Within his paintings, you could see famous prostitutes, hoboes, represented as saints, such as Mary or St Peter. His life has multiple legends around it, he was known to have sexual relationships with both males and females, while painting for the Church, and his competitors tried to destroy him for that. He had to flee Rome after killing (accidentally?) someone and lived in Naples, Sicily, Malta, etc. The story of the movie is a bit long, but this is not why you should see this movie. The whole movie is staged as a painting, with that kind of atmosphere that you get from 16th century Italian paintings. Would I watch it again? No, but I am happy I watched it.
