This movie tries to be something mysterious but fails miserably. It became a trend in last few years in Hollywood to make movies with no story, meaning. The lighthouse takes this to next level. Everything is left unexplained and open ended. This will bore you to death. There is no way it deserves any praise. This is the kind of movie that makes me wish there is option to give negative rating to movie. It deserves less than zero. Don't waste your time on this pile of garbage.
