I agree wildly and I'm seriously shocked that the guy above is arguing in favor of it. I can't stand the weird motion smoothing on modern TVs and would not buy any TV where it can't be turned off.
I'm not arguing in favour of frame interpolation at all. Footage that was shot at 24 FPS should be displayed at 24 FPS. But footage should be shot at a higher FPS.
I could probably get behind that, I'm actually somewhat curious now if it's the higher framerate or only the algorithmic "motion smoothing" that causes the famous soap opera effect.
