Original and unpredictable, this slow film comes to life in the middle third on the yacht. The rest is pedestrian if interesting.
As for the heavy handed instruction, we know that the rich are privileged and generally selfish. This point did not need to be simultaneously hammered home and rammed down the throat.
The first third is dispensable while the ending is unsatisfactory.
However, it's original and, at times, enthralling. But definitely not for the entire 2+ hours.
