Vu en salle.
What starts as an original journey featuring many inventive moments is rapidly taken over by some "growing up" story told with seriousness and with its own moments (like that interphone scene where there seems to be some hope beyond loneliness in the city) but leading to nowhere.
The few flashbacks and their focus on sensations and tying things together are nice, but the main appeal is the sound design.
Aside from that? Nothing. But it's already a nice lot.
Score: 7/10
Enjoyment: 3/5 (all that thing with the girl became rapidly uninteresting)
PS: also, please stop with that "romanticizing a stalker's behaviour" thing.
