Maybe, I am over analyzing the plot twist at the end but there’s are a lot of loose ends and potholes with the plot twist. I honestly loved everything right to that point but so many questions arise from there on out.
Example
1. If the real girl was taken under, why did she never escape and why didn’t she never mention it when she met the real shadow.
2. Why does the real one talk like that, yes granted she is the only one who can talk amongst the replica people, yes fine she hasn’t been able to talk for while so maybe that’s why her speech became impaired
3. There was no explanation for how the Shadow was controlling the real one below
4. How come the kid is now suspicious of the mother? What did he see or hear?
So many other unrelated questions in relation to how it ended esp in relation to the underground living, it should have been another dimension
