I finally watched Snowpiercer, it was actually OK for me not being a fan of that genre particularly. The part where they first get to the children's school car, or whatever, is really jarring and surreal and I thought it was really clever in the middle of the film.
It was a little on the nose about obvious political analogies, but all and all, I did not feel like I wasted 2 hours on it. Solid B-/B.
