You really cant ask for more Masterpiece by every standard. Canet has taken it to a new height having achieved the perfect mix of human emotions entwined with suspense and thrill. At no point in time in the entire 121 minutes do you ever have that dragging feeling. François Cluzet was at his amazing best playing the suffering husband but the star of the movie without any doubt was Kristin Scott Thomas. This is how great actors make everlasting impression in a movie even without even a major role.
Despite being in French, the English subtitles without ever being intrusive and imposing, never let you lose the feel and emotions. Compactly plotted, beautifully directed and acted, its worth every minute of what other wise seems to be a lengthy movie.
If you want to spent a quiet Friday night with your spouse, rent it and watch it. It ll give a new perspective to your lives.
