Hard disagree on Solo miscast leads and a leaden script no matter who the director was it was in trouble, especially considering the actor is not Harrison and they killed him like he was nothing in Force Awakens, way too late to make a prequel for a dead Han. Might as well have tried to sell dead Han toys.
As to moving the timeline from 3 to 2 years between films I do somewhat agree, but I also agree throwing out Lucas outline and then having no plan was a problem as well.
