NO REALLY!
I agree it's not quite as electrifying as Get Out, but expectations were so high that's to be expected. After some thought, I realized that Us is a parable of alt-right paranoia, and the fear of being replaced - you know the South Park joke "THEY TOOK 'ER JERBS!" about immigration, and those polo-shirted tiki torch dudes shouting "Jews will not replace us?"
The most chilling line when the doppelgangers are asked "who are you?" the answer is "We're Americans." And they're looking to take the place of their topside alternates to get all the "good things" they're afforded by privilege - and a view of the sky. The tethered share a soul and are compelled to act out a weird counterpart of what their double does underground...
But the twist - the mother (Lupita Nyong'o is stunning as Adelade and her terrifying counterpart, Red) hasn't been afraid because she escaped so many years ago, it's because she is the doppelganger who switched places with her topsider counterpart as a child and isn't interested in going back. The character we've been rooting for is one of the ones we've been made to assume are the enemy, and the only difference is privilege of being able to live somewhere with a view of the sky.
