Poorly executed horror that fails to make its central theme clear

Rating: 1/10 (2 March 2019)

First things first. This is a very poorly executed horror film. The pacing is terrible. The dialogue is extremely wooden. The horror elements are not very gripping or startling. The characters are one-dimensional (except for maybe the main character's best friend). Compare it to the absolutely excellent Rosemary's baby that has some similar themes and note the differences in quality for yourself.
So, why did it get an oscar? Maybe because it tries to make a point about race and that this is something unusual in a horror film. Maybe that is something unusual/different, but the message itself is not a clear one. Is it supposed to be saying that positive discrimination or attempts at structural reform still perpetuate an insidious us/them attitude? If so, the point is not very well made and gets pretty distorted by some of the cultish elements.
