If it’s gotta be a film trilogy and be less andor mire rotj, focus less on anakin, he’s there and a major character but Obi Wan is the main. The first episode is obi Wan and his new apprenric Anakin doing some jedi bullshit and discover a threat! Some weird aliens thst can clone themselves and be basically an unlimited army are a-comin! The republic reacts to this crisis, gives Palpatine the emergency powers, this clone army is relentless and eventually society becomes more and more militarized and people are drafted into being storm troopers, politcal control increases etc. The clones run dry, the empire is now a thing without anyone really noticing it happened. Maybe Palpatine orchestrated the clones maybe he didn’t, doesn’t matter much. Anakin goes dark side somewhere over the course of this but by the end circumstances have led to the jedi being pretty dark as well during the war, he just didn’t let it go. The remaining jedi wh ogot their shit back together after the war are then mostly killed by Vader. Add a compelling cast that gels as well as the OT and add their personal stories and that pretty much fills out three films.
