So many plot holes.

Rating: 4/10 (25 May 2019)

Cinematography was awesome, premise great, feel was perfect. I even liked the idea, if not the execution, on the doppelgängers and "shadows" thing etc.
But how did the shadows survive etc? Get clothes? Food?
It's stated that the tethered were abandoned, so how could that happen?
There's doppelgängers everywhere being led by her? How?
And sure, let's say she was forced to the same guy in doppelgänger form, but they then actually have the same children?
I had no real issues with this movie until the end. I would have preferred a supernatural explanation, or "hell" or something, as the explanation we get is just.. full of holes.
