Snowpiercer

How can it be that I've only just seen Korean director Bong Joon-ho's sci-fi masterpiece "Snowpiercer"?

No, it's not a perfect movie. But it's ambitious, momentous, surprising, inventive, comical, political, bleak, horrific, gritty, wacky, micro-cosmic, Tilda-licious, thought-provoking, eye-popping, pulse-quickening, hair-raising, high-concept-meets-genre, survival-drama-on-steroids. It's effing amazing.
