For the record, this is not a Horror film. Everyone who watches it in expectation of horror will be disappointed. There are some mysterious events, and I must say, that I liked this aspect the least about the movie.
In The Fire is certainly not a bad movie. Neither are the actors doing bad, nor is the music out of place. Yes, the script may be a somewhere immature, not actually made by a master of the art of writing.
It leaves a number of things (like character backgrounds) untouched, and instead focusses on the boy and his strange mind, and how the presence of a well-meaning, understanding and caring person benefits him.
The movie tries to capture the atmosphere of a time and a place where education was mostly absent, and where superstition still could reach the minds of people, leading to cruelties.
Set and location are great, some things are weird, for instance, two priests on opposite sides, a farming "Don" with two servants, who does the work of a peasant, but can afford a personal shrink from the U. S. for his son.
Direction is ok.
I understand that the outcome of the story is somewhere unsettling, and also sad, but it is a story that is told with enough love and effort, so that I was entertained and not bored.
Six stars.
