To even have Greedo shoot reflexively as he dies fundamentally changes Han from cold blooded to standing his ground. To have Greedo miss a 3ft shot so Han can justify a response is just laughably bad. Han’s redemption (returning any the end to save the day) is cheapened by the fact that he’s not the cold blooded, do anything to survive, scum of Moss Eisley as he was in the original theatrical release.
