A russian War Film called "Come and See"
Three hours of watching a young boy being mentally wrecked by the atrocities of War.
Gruesom, fucked up but incredible Film
Just watched that a few weeks back. Took years to psyche myself up to watch it, due to it's notoriety. It wasn't as bad as I thought it was going to be, but it is NOT for the faint hearted. Truly a masterwork in acting and cinematography. The sound, in particular, was haunting and dissonant.
