Um what? Why?

Rating: 2/10 (8 March 2020)

Spoilers spoilers spoilers ahead I want answered!
First of all, loved the pop culture references made, the music was fantastic and the idea had so much potential. However, that's all that was good about this movie.
So many plot holes where do I begin. When you have to have so many plot holes just for a higher meaning in the overall theme it falls too flat.
So, spoiler one...if the evil doppelgänger knew there was potential for the real one to escape back into the surface world why in the hell would she return to the city and beach she traded places with her in the first place? Why not get as far away as possible?!
Next, why is the husband so weak and dumb. After seeing they are doppelgängers he continues through the movie as if it's something it's not, like he can't wrap his mind around the reality of what's happening.
Why did the actor make the choice to use that voice? I had to explain what was going on to family members because we had a hard time understanding what she was even saying!
Also, why did she not escape when she was a child or out the doppelgänger when they were face to face?! I don't understand why she couldn't escape a place not that hard to find your way out of and no guards or locks of any kind present.
How had no other doppelgängers escaped before in all their years down there? Or no humans finding the doppelgängers down there?
Why surface to kill and then just stand in a line?
So many more things didn't make sense at all!
I get Peele had an overall larger meaning to each and every detail, but when the explanation and the plot holes don't make any sense for the actual storyline ( like how only selectively the doppelgängers had to actually move like their counterparts without choice or only selectively felt what their counterparts felt based on the circumstances) drove me nuts and it ruined the movie for me. If you want to make a big statement write better scripts. The end was lazy and not even thought out enough to be believed in the movie universe. Too bad, I really enjoyed Peele's previous work. He got to pretentious and in over his head with this one and rushed it.
