So slow it induced an irrational rage in me that I shouted "mooooovveee" at my laptop screen as Lily sloooowwly walked down the stairs in the last scene. I can see how it's meant to be a chilling and tense atmosphere, creep inducing type of artful movie, but they overdid or underdid something and it just ended up being a quiet slow moving hysteria. Burn it and never show it again.
