Just an awesome movie, stays away from many of the corny tropes and manages to create such suspense and tension.
Greta Lee especially brings such a subtle, nuanced touch to her character. And the acting is amazing. A lot of the best acting happens without words through fleeting glances and long silences.
My girlfriend convinced me to watch the movie, and I was skeptical at first but after watching it this is one of the best films I have seen in recent memory no doubt.
