Rey and Luke kind of work on the same level as characters. Rey’s not as strong as she didn’t have the wanderlust or tragic loss Luke had, but she’s ok.
Kylo Ren is nothing to Darth Vader. Unfit to clean Darths boots. I’m not sure of the thinking when creating the character, but it feels like they took every bad idea and no one was there to tell them to stop.
And Poe is no Han Solo either.
I remember the prequels only getting hammered after the second movie came out. A lot of sins were glossed over in the first movie. I wonder if the same might happen here.
