Incendies
This is easily in my top 3 Denis movies along with Sicario and Blade Runner 2049. It's so good that even when you figure out the twist early which many will do, it still hits so hard when it lands.
My main criticism is the extent to which you have to suspend your disbelief is probably a notch too far for me. Even in a movie as grounded as this feels, it's still so implausible that you have to ask yourself "...really??".
For that reason I give it 9/10
