So first of all: the actors. Yes Uma, you did good, but what's up with the twenty-year old highschoolers? The unkle? The crazy attic-lady? Wow- how people think this is good acting escapes me. I had to burst out laughing at a couple of scenes and lines.
Production value? It feels like they ran out of money after the first episode and only had money for a simple red filter that they needed to use in every "scary" scene.
The plot is the dollar shop knock-off version of "Hereditary" (which I loved), and was trying hard to be something that it is not.
I will grant the three stars because I did finish it and it was a fascinating waste of Netflix money to watch in a "what are they even doing" kind of way.
