The beginning is unnecessarily suspenseful. Almost to the point of being forced. There is no proper explanation of anything and it just continues on till the end when you see some correlation. Usually when you hire house help from overseas there is an agency involved, background checks, onboarding etc. All of that has been brushed under the carpet. No doctors involved at any point to help the main character. Just too many plot holes. Then there is the cinematography which is again unnecessarily ominous. Once the movie finishes, you do feel a bit cheated. The best movies are ones which are at least slightly tethered to some form of believability. This one unfortunately is far from any.
