Critical Dissonance: The film holds a very high 90% critical rating on Rotten Tomatoes, but a more lukewarm 66% audience rating, obviously due to the slow, minimalist presentation.
Esoteric Happy Ending: If only disappearing at last can be considered a happy ending for a ghost. It is strongly implied that this is the case in this story as the ghost was trying to take out a note his former wife left inside the crack in the door-case. Then after he succeeds to take it out and reads it he disappears.
Narm: The "sad eyes" on the ghost when his wife finally leaves is kind of silly, despite the sad moment.
Signature Scene: For better or worse, the most talked about scene in the movie is the one in which Rooney Mara eats a pie for four minutes while the camera makes the audience watch the entire thing in one unbroken shot.
Slow-Paced Beginning: The first 25 to 30 minutes are agonizingly slow, as theyre filled with long, mostly uncut scenes of silence or other mundane activities (including C and M sleeping, a long shot of Cs body in the morgue before he revives as a ghost, and the infamous pie-eating scene mentioned above). However, the movie picks up once C meets the other ghost and further notable events follow, better emphasizing the movies themes of passing time and mourning.
Visual Effects of Awesome: The movie's pretty light on effects, but the sweeping landscape shot of the Mega City as the ghost leaps off the skyscraper is nothing short of gorgeous.
