Ian Shade’s review published on Letterboxd:
We are all far more and far less complex than we fancy; Peele’s consciously-superficial parallels are just expressions of everything that we already express, jejune and obsessive and expected of everyone. When we say "actions have consequences" we always mean bad actions, when that reality hews closer to the whole of it, everything we do to other people and everything they do to us. The totality of life, reinterpreted as a dread Omniscience and the invocation of God. There’s a lot they can’t understand, but someone out there does, and beyond the "better version" of yourself is what you can’t understand about what you’ve done, and why the outside world responds with a pair of scissors and the color red. From the mirror-actions and mirror-desires of the Tethered, I recall the shock and cringe and brain-scramble that occurs whenever I hear a door slam, whenever someone raises their voice above neutral--and of course the where-do-you-get-off shame that attends that response ("she wasn’t in 'Nam, she was lost for fifteen minutes"). It’s too much, it’s too much. Still, even with that mind, your conclusion is a cheat, Jordan, and you know it; our culture is already so preoccupied with the concept of twinning that even the most brilliant sense of self-awareness won't stand up to something so damned obvious.
