Somehow all efforts from episode 4-6 were in vain and Anakin wasn’t the chosen one again because throwing Palpatine into the death star core didn’t have any impact on anything. Somehow they made everything Luke, Leia und Han achived pointless. Somehow cloning was easily achievable with some dark powers and somehow Palpatine cloned himself and chilled for a few dozen years. Somehow Palpatine was a father and somehow Rei was his granddaughter.
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.
