I like the characters, I never saw them as anything more than what they are.
Truth is, and the truth hurts, the OT characters are kinda flat also. People lile to talk about character development, but most of the main characters in OT had an arc with maybe a extended branch on the main arc.
I agree. The OT is not Shakespeare. But I had a more vested interest in what happens to them. Han had that whole subplot with Jabba that always held interest. Leia and Han's love story surprised everyone back in the day. And there was the possibility (however unlikely) that Luke would turn to the dark side, and if not, how the heck will he kill his own father.
In the ST, my only curiosity is what's up with Rey. What path will Disney ultimately take with her? Kylo I've known from the beginning. No one else has a subplot that has set-up any upcoming conflict.
