My review after some thought

I went into the movie not knowing much about it besides the trailer. I haven't read any think pieces or gathered much information concerning the meaning behind the movie.
I think the one thing I did was go into the movie looking for clues, Easter eggs, etc. trying to outsmart the movie instead of just watching the movie.
From a surface level review of my thoughts, there were a few things that stood out to me.
The scripture gave a clue about what was going to transpire. The evil they can't escape is within themselves so in a sense you can't escape yourself. The shadows(below grounders) were being portrayed as evil or maybe an alter ego but contained within the depths of the subconscious imo. However, since Addie was switched out she had the ability to break through the subconscious and assist the others. She was a little girl when her mind was taken and assimilated until she was able to remember her truth. I just think shadow Addie was lucky and things came together at one time to allow her mental escape.
I think it was all mind over matter and the above grounders were allowing their shadows to overtake their consciousness.
The boy and girl were able to outsmart their subconscious because they were the children of the shadowed Addie so there was an evil inherent trait in them. You saw how the daughter was killing folks and the boy outsmarted his shadow. The husband didn't have a clue but maybe lucked up by banging his head to start the motor that I believe hurt and killed his shadow.
(He did that earlier in the show.)
The other thing that stood out was the family was very suburban and lost all sense of street smarts or cultural interaction like turning to God, praying something, looking for holy water, oil, nobody strapped.?? It's like all common sense/street smarts went out the door.
I thought it was more of a psycho thriller because it was more about mind control imo than the physical that was presented.
The physically dead bodies were a representation of the shadow's overtake of their good consciousness and that basement dungeon area was the mind/ consciousness Imo
