What the fuck
This is the kinda movie to go into 100% blind. It's the kind of movie where you can predict what's going to happen a bit before it actually happens because it's pretty methodical about what it shows the audience. To some people this may take away from the experience but for me having a good inkling of what's going to happen added to the tension so much. Anyway good movie, but you gotta be a specific type of person to like it.
This is a fairly rare case of a movie that I feel manages to perfectly convey everything it wants to convey.
My only (very small) problem with it is the fact that quite a bit of the soundtrack feels a bit listless, merely being there for the sake of being there, but the rest of it is used really well and the sound design is pretty goddamn superb
