Review: "El Mar" directed by Catalonian director Agusti Villarona, and based on the novel by Blai Bonet, offers a glimpse of the Spanish history as seen by a Balearic author that takes the viewer back to the days of the civil war in that country. The movie concentrates on three friends, and follows them from those early days during the onset of the war in Majorca, to a few years later as two of those friends meet again when they are at a sanatorium, lost in the countryside.We first meet three boys that are playing happily. Not everything is what it seems. The tragic death of one of them points out about the cruelty of the one that commits the evil deed. The boys have excluded a young girl, about their age, from taking part in their games.When we meet the adult Ramallo again, he is on his way to a sanatorium. He seems to be suffering from tuberculosis. To his surprise, Manuel Tur, one of his boyhood friends is also being treated, and the young girl that was not welcomed to participate in their games is now one of the nuns that supervise their health care. It is obvious that Tur looks at Ramallo in a way that only means he is in love with the tough bully. Their relationship will have devastating consequences.Roger Casamajor does a good job with portraying the older Ramallo. Bruno Bergonzino makes an impression as Tur, the vulnerable youth. Antonia Torrens plays Sor Francisca with conviction. Angela Molina, puts an appearance as Carmen, the wife of the caretaker of the institution. Simon Andreu is perfect as Alcantara."El Mar" is a dark film that clearly shows Agusti Villarona's talents in making the novel come alive for the viewer. Question: is it a positive review?
yes
