A powerful feature film. Despite some reminiscence (group of friends, dinner, the house atmosphere, colors) with "Coherence" is undoubtedly an original movie. A very interesting point made by the director (who had already done Girlfight and Jennifer's Body) over a possible processing of the pain of a loss, in a quite denying way, perhaps cynical, reaching extremes of aggressiveness. A lot of tension, making us doubt who you believe (or even what is real) at every step, until the crux of the matter comes; you may wait a little for that, but it's worth it. Point for the director for not using low blows. Worthwhile if you want to spend a very intense time. With regards to actors' work, "Will" comes out unscathed. "Eden" maybe a little artificial, but I think it is an intentional nuance given by the director. The rest comes off well. The screenplay is pretty good. Although it is not revolutionary, the pace is accurate, keeps the suspense, and plays with ambiguity.
