First half suspense atmosphere build well, thought that familiars are religious, good at sainz, deprive a person lives, middle leading role, and the boy both drama and begin to reverse, she finally back on track, lost people are still in life, life in the sun is shining, seemingly everything, however, the second half of the black background and pull up, she is still in the difficult, All the images are just the boy's brainstorms, the whole movie is logical and self-consistent, but the later part is too tired, it becomes a pure fantasy with no real meaning, suddenly lose everything built before, there is no surprise ending processing.

Suspense design is quite careful, especially the deep digging of freedom consciousness, and even can be said to be relatively romanticized against the existence of absolute authority.
