Agree on the female protagonist thing. Plenty of good female protagonists throughout history. This one just sucks. And kylo, Rey, Poe and Finn aren’t interesting characters because the writers and casting directors screwed the pooch with all of them. Although with Poe, I’ll blame the writing and directing because I think Isaac was a good addition to the cast.
Thing is about the prequels, they still gave us good characters. Padme, anakin(to a lesser extent because Christensen wasn’t great), Kenobi, and Windu were all good characters. Jar jar and Grevious were bad and both on par with sequel trilogy characters though. Lol.
As far as being exhausting, why? Disney felt like it was worth a 4 billion investment to buy and the additional investment of building a world in their theme parks. If the franchise was batting 2 for 6 as you say, Disney wouldn’t have bought it. The fact is, the World wanted more Star Wars, Disney saw an incredibly large market, and they gave the world a shit sandwich. It’s like a RB with a gaping hole, breaking through it and has 90 yards of empty field in front of him, only to fumble the ball with no one around him.
