Wow, i only heard about this yesterday, it's French and you'll need English (or whatever language you want) subs unless you know french haha.
I'm usually never into films like this but wow, it's got like every emotion in the film, it's really really good and very moving. I very very rarely get emotional in a film, but well i did in this, don't expect some depressing film, I'm not giving it the justice it diserves here, just go and watch it.
