As someone who loves motion smoothing; I'll never understand this opinion. It doesn't make everything look like "crap", it makes it look more realistic. Motion looks closer to real life. Hell, I like it for the fact that it removes motion blur alone. Can't stand motion blur.
Trying to go back to watching films at 24Hz is nauseating for me (especially action movies with a lot of rapid camera momements). I can't stand it. It's like trying to go back to console gaming after getting used to 4K 144Hz PC gaming with a 4090.
Try leaving motion smoothing on for a week and then go back to having it off, and you'll see what I mean. You get used to it, and then suddenly you don't want to turn it off anymore.
