Saw this today as part of the SIFF winter series with some friends, and I was very impressed.
Edit: Ok, fine, removed spoilers.
The characters are believable everyman! Little sentimentality. They give screentime to people just walking around the room! That suffocation scene was exquistely unpleasent, too.
Some of the acting was pretty comical by today’s standards, though. I burst out laughing at the expression on Mathilde’s face during the final scene.
