For me it’s the scale and perspective that stood out first. Both people are the same size on-screen but the one on the right is also supposed to be closer so they’re actually huge, but they also have a tiny chair. Both chairs are also pointed away from the TV which is as big as a person, but they’re also somehow not facing each other so the closer person still has to turn around.

It just feels very strange as someone with first-hand experience of 3d space.
