Wanted to watch a horror movie last night and settled on this; wasn't exactly what I was in the mood for (it's more unsettling than creepy), but I liked it quite a bit. More than anything it felt... plausible? Walks a very narrow tightrope of negating self-awareness, where you're constantly aware that everything the main character is experiencing could be made up or real or both--actually, it's probably both, saying otherwise would be to miss the point. The sort of movie that takes a shlocky premise (a YouTuber gets involved with an Internet urban legend) and underplays it to the point where you're never quite sure what's happening, if anything's happening at all. Ambiguous all the way down, including an ending that haunts me the more i think about it.
