I liked the ending and few funny things typical for young people, except bit unreal and extreme. Makes us aware of our obsessions to phone and how they can or can not replace people. Few cool things in form of talk and revenge. Also liked that unlike in most other things that everything looked real (cat, stabbing, burning, blood). But everything else is so unexplained, unfinished, unclear, ignored, without any reason. Meaning bad story, has so much holes that makes us wonder the purpose of all the happenings. Maybe this horror is best suited for younger people or kids who believe in magic and do not ask questions. I liked that movie is about our current problems and technology, so makes it more interesting.
