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.
