shibas are crazy tho

If you make a movie you make it with multiple audio tracks (lines), often there are dozens of lines for cinemas and more for IMAX. If you mix all those lines together, e.g. to 5.1 for home cinema you'll lose dynamic range. Now if you mix it into 2 lines (stereo) this means you basically have everything (explosion, whispers) on the same two lines for left and right and that's why you either need at least a front speaker for dialogue (so only effects are muddy but voices are clear) or bear with it.
