I really looked forward to this movie, which I thought sounded like it was going to be a remake of an old version which starts out very similarly with a married lover, this time the boss's wife, being the actual witness who refuses to step forward when she was witnesses the attack
Mireille Eros is a particular favoririte of mine and she doesn't disappoint here either. She is the consummate professional, through and through.
However, she alone is not enough to save this mind bending tale of twists and very mysterious turns.
Another reviewer here on IMDB is the master of the understatent when (s)he proclaims,
"While the ending is left subject to interpretation.". Interpretation, indeed. My idea of being left to draw my own conclusions runs along the lines of do they get married or not, or, does the bad guy get caught eventually, not summing up the entire plot point! That's a fatal writers flaw, and let's not forget the director, whose vision it should be to bring this tale to life. Consider it a vision only partially inflated, and then perhaps a little run over by a truck. Perhaps another director would have brought it together into a cohesive experience instead of a confusing mess.
I would not watch this film again and that's poor praise from me. In fact, I'm sorry I watched it at all, and I seldom say that.
Take your chances if you will.
