As of this writing I am still confused on how, when, where, and who (which I think may need another screening of the film to get some additional comprehension from clues and symbolism hidden with every scene.
From the title itself, it does have a relation of having a third person narrating the story, but not all of it. It's like inception with layers of other worlds yet still connected to each other as way of convening to their common denominator.
The casting is probably the best things about the movie. Leading the cast is Liam Neeson which plays the writer and the central character in which all are linked to. Some may think there is an element of thrill to the execution of the movie, well there is but very subtle. Reactions would also vary from they way you may view things.
