Object based sound is good in principle. The demo clips we've all heard are proof of that. The ones where Dolby goes from 5.1 to full Atmos shows the power clearly.\n\nHowever, in real world content it's simply not a big step up compared to simple upmixing. Movies are too loud, there's too much going on the screen, in the audio everywhere for you to even notice the location of sounds. Therefore, upmixing suffices and accuracy isn't an issue. The bubble is what we're enjoying and it doesn't need to be discrete.\n\nAn example of where a film really did use Atmos well was Roma. Good article on it here: Roma’: Alfonso Cuarón Proved Dolby Atmos Is the Perfect Tool for Intimate Films, Not Blockbusters. It was a quiet film and the sound really put you into it.
