Lucky Bergman was not French! Not hard to imagine what a modern day French filmmaker of the likes of Gaspar Noe (Irreversible, 2002) would have made of this quite violent theme. Not to be watched if you are feeling a bit low!
My own fault really, I picked a film by a Director that I'd heard of but never seen before, and without really looking to see what it was. This is a dense arthouse film which relies on the viewer to fill in some big gaps in the plot for themselves. If you know the Director's themes and obsessions it probably all makes sense. If you sit down and watch it cold without having read up on it then you will, like me, find yourself heading for IMDB / Wikipedia to understand what on earth it all meant after it finished.
