I feel like Cosmonaut Variety Hour’s perspective is a pretty fair assessment. He likes all the Luke/Rey/Kylo stuff, but he feels the Finn/Poe/Rose stuff is pretty weak in comparison.
RJ said he created Rose because he felt Finn and Poe had the same voice, but imagine the Rose and Finn conversation about war, but Poe took Finn’s place and Finn took Rose’s place. Poe likes being the hero and does whatever he can to win, but considering Finn is a literal child soldier, he knows all about the costs of war.
It’d come at the expense of one or both of their arcs, though.
