Vulture:

Whether you’ve realized it or not, you’ve likely watched a movie in motion smoothing. It’s nearly impossible not to, as it’s now the default setting on most TVs sold in the United States. And however well-intentioned it was, most people hate it. Motion smoothing transforms an absorbing movie or narrative TV show into something uncanny. The very texture of what you’re watching changes. The drama onscreen reads as manufactured, and everyone moves like they’re on a daytime soap — which is why it’s sometimes called the “soap-opera effect.” In other words, motion smoothing is fundamentally ruining the way we experience film.

If you’ve got a “fancy” TV, turn off motion smoothing now.
