In the recent horror film Await Further Instructions (2018), a family is trapped in their house by a mysterious barrier, which is later to be revealed to be part of some kind of strange monster which is made up of thousands of black wire/tentacle like things coming out of the TV sets.
The monster causes the father to torture his family and eventually they all die except for an unborn baby, which the monster causes to be born by disintegrating the body of the dead pregnant sister. At the very end the baby is alive and the TV set shows a message to the baby - "Hello Ruby" - after which, the camera shows the exterior of the house and we see the whole neighborhood is also covered in the black mass of tentacles and I assume we are meant to understand the similar stories have played out in the other homes.
So what was all this meant to accomplish? What exactly was the black tentacle monster, why did it want the family to die and the baby to be born?
