The problem with the movie was that a lot of TV watching people see it as a “soap opera effect” because those are shot in 60 fps. So they don’t like it and want a “cinematic” feel.
For me who doesn’t usually watch TV it was glorious. Yes, you notice every tiny mistake on the screen at 48 fps, but it actually feels real. Like that’s a real dwarf there talking with an elf for example. More lifelike if you get what I mean? It’s a damn shame you can’t buy the movies with HFR :-/
Well, 144hz has more than one benefit. You get a smoother image output of course, but also less input lag (seeing actions you take faster on the screen). But switching between the two is very obvious usually, even when just moving around a window on the desktop.
