The theme is far to be new but it is wise crafted in this case. Because it gives the illusion to know the story. Because it gives a beautiful meet between librarian and Ariel, performed in beautiful way by Raquel Houghton. Because you feel the end before the lead character and the confirmation is not just nice but it gives the answer to the dialogue with the librarian. A well made film about a classic urban myth. Exceptional because it propose more than thrill and cries but a real interesting - provocative story.
