It’d be sad to lose the Luke and Reva tension, as I’m usually up for a halfway decent redemption story.
There aren’t any redemption though since there was no reason for her to come after the boy to create a forced tension only there to mimic Lucas parallel montage. And to show Beru as a badass character (because it seems every female character has to be a Ridley/Sarah Connor figure now even if it has nothing to do with the already established character). I can’t think of anything making any sense in this entire subplot… cutting it entirely is a fine decision by all means.
