That was me mate. Think you said you bought it for your son if I remember right. Same director Denis Villeneuve as 'The Arrival' mentioned above, which I can't say I enjoyed though it was thought provoking. A few other films really great films he made which I like are French Canadian film "Maelstrom", "Enemy" and "Prisoners". Think the last one is on Netflix.
Seeing as you like Incendies, I would recommend an Iranian film called "About Elly" / "Darbareye Elly". But go in blind and don't read up on the story if you can.
Amazing / nasty film.
