I think the movie tied everything together splendidly. Although I don't like the grudge-ish monster that was created towards the end, I am attracted by the underlying plot. Pyewacket as stated by Rowen is a being of manipulation. Manipulating the daughter to do it's dirty work for it was absolutely genius to me. The movie doesn't throw jump scares at you like most present day films it savors them, the movie overall has a genuinely eerie vibe to it. 5/5 from me.
