I found it very annoying not knowing half of what the actors were saying because they were speaking in French throughout the entire movie. it really took a lot away from being able to enjoy the movie. The autopsy was all in French, the son spoke in all French as well as the investigators/police personnel, the journalists/reporters and the mother's lawyer. He spoke to her in English but to everyone else in French.
It was odd when the mom spoke to the son in English and he replied in French. What's up with that? Then we go into the courtroom and everyone is speaking French! I found it difficult to follow along without the details being given in English. I had to turn it off. I'm very disappointed I wasted an hour watching up to that part of the movie.
