The real reason Paper Jam sucks isn't because of the Luigi hate or the flanderization of Starlow but because the game completely forgets all prior character growth from the previous games. For example, at the end of Dream Team, Luigi has become so confident that Giant Bowser and Antasma don't scare him. Yet in PJ, all that growth is gone and Luigi goes back to cowering behind Mario and Starlow like in Bowser's Inside Story. This can't simply be explained away as "ok because of a 'sequel reset'" because Brothership subtly continues his character arc by having him throw out crazy ideas with full confidence and being able to go along with ideas he doesn't like. Like you can choose to have him be kidnapped and although he still has some fear inside him and doesn't want to do it, he ultimately goes with the plan because he has become fully confident in himself and his brother as established by Dream Team. And no, I'm not looking too deeply into things because Bowser Jr.'s arc from the Jr.s Journey mode that like 2 people completed where he has to become a better leader and friend continues in Brothership. That's my big reason for why Paper Jam is ultimately garbage.
