Yeah, I need to see this again. Cool editing, cool cinematography, great music and fantastic acting.
But I don't know. Much of the times the film was trying to be a bit emotional, fell flat. Per example, in the opening scene, the slow-mo scream of John was terrible. When Heather was screaming "YES YES YES", the way the phrase "what did she say?" was repeated over and over kinda made it goofy. And for the love of God, that gratuitously long sex scene, as well edited and scored that it was, its so absurdly unnecessary and awkward, and it was by far the worst part of the film.
I liked the mystery involving the film and the sense of dread (that was a bit fucked up by this goofy moments), but I still can't align my thoughts on the narrative, so a rewatch is in the works.
