The problems, to my mind, with the middle build of The Force Awakens? Rey doesn't choose the Millennium Falcon. The break into act 2 should be an active choice. She does choose to leave, and it's okay that it's a best bad choice (leave or die), but that thing where she isn't actively deciding to take the robot back on the Millennium Falcon? She's sort of a passenger through the WHOLE middle build in every regard. And that's a problem.
But everything from bumbling onto the Millennium Falcon until roughly act 3 is pretty formless. It's okay, but compared to that opening? WHEW, it's a step down. They coulda kept that momentum with just that tweak (and a lot of tweaks to subsequent scenes as a result).
General Communism, writing, and shitposts.
