They just need to pick the ideas and elements that worked before and expand them. For example the best episode of the Mandalorian was the Wages of Fear/Sorcerer fuel transport depot story. A tight action set piece followed by a decent character moment. Instead of muddying the waters with yet more Jedi nonsense and failed attempts to add nuance or new dimensions to the Force, just start with classic movie homage. They did the Dam Busters, so they can do Battle of Britain. Or Cross of Iron. Or Kelly’s Heroes. Or anything. Star Wars itself was always a ‘steal from the best’ situation after all.
