What is most interesting is how close the film comes to horror in its third act. It is as intense as any full-fledged horror film you are likely to see this year. They turn the suspense up to 11 and then rip off the knob.
This is not the first time we have seen this technique, of course, as the Unfriended franchise relies on the same method. The difference here is that it never feels like a gimmick.
There is nothing here beyond what is on the screen and what is on the screen is an unbalanced, ill-conceived, melodrama that is wholly lacking anything that feels fresh or original.
