The argument scenes were very strong, reminded me of Scenes From A Marriage and reminded me of a world I never want to enter
the setting is cool, the small details interesting, everything is good, very European-- but the movie didn't really move me, or hit that rush for me. I walked away kind of unscathed, but interested. There's a theme in there about the essential "unknowability" of a person even to themselves and their partner. Or children. There's something like that, but I have seen that before too.
Not saying it needed a mystery, or a antagonist, or a twist ending like High Crimes, or Jagged Edge, or a dozen other marital thrillers, but thinking back to when I saw this, and I can't remember if she did it or not, or what the movie implied.
