I thought it was completely boring. The accents were hard to understand (which I suppose was intentional, but it added to my dissatisfaction). At one point, they just showed the dash board of a car for like ten minutes. Whatever the point it was trying to get across was lost on me. The end--while to most interesting part of the movie--did nothing to bring it together. It basically had less of a plot than it did dialog.
I'll add that I am a fan of Kubrick, Sci-fi, Johansson, & artsy films, but this one was unwatchable.
