There are definitely some references, like crack in the wall, but the crack thing goes in a completely different direction. In Repulsion, Deneuve is over the top, simulacra of madness, here, she's a regular patient, no wild insanity thing, it's pretty ordinary, by the book. But everyone in the movie is a bit crazy, in some dark comedy kind of way. Little neighbourhood is very well depicted. Ending is, however, not very good, lost points for me. Something is missing there. But still, a nice movie. Good acting, interesting characters, some weird scenes, there's a lot of cute stuff, but that ending is haunting me. Too weak, to dry, too short, no real closure. Why?
