Way too conveluded. This movie is a utter waste of time. They took a paranormal, monster, psychological thriller with a way to long of a setup, for the plot to be even more apparent.
There are certain jump scares that were ok. This movie wasted 2 hours of my life.
Spoiler
Non Conjoined parasitic twin takes over sisters body and murders people. THAT'S IT. This film is terrible.
