phaolo: Ugh.. we did grasp its point, but also its horrible realization.
(RO minor SPOILERS)
I would have frankly preferred another Darth Maul-like Sith, instead of that angry powerful teen (what an underwhelming lame twist).
Yeah, I thought Krennic on RO was a bit of a sniveling shit as well but still managed to be menacing enough, as opposed to Kylo Ren. Of course they couldn't make Kylo Ren too much of a bastard because that would ruin his redemption arc in Episodes VIII - IX, if everyone hated him.
Having the sequels a bit too much in mind I think was a bit of the problem with The Force Awakens, and I put the blame squarely on JJ Abrams. Have you ever seen his "Mystery Box" TED Talk? He speaks of crafting stories like a mystery box, to always leave people guessing about stuff. It's the same thing he did with Lost, and in a way it works, it's great for driving up audience engagement, but it's a tool for creating hype, not good stories.
I see this mostly with Rey. She does come off as a Mary Sue in the film, in that she is more skilled in the force, lightsabers, etc, than anyone else for no apparent reason. I imagine there is a reason for her to be like that, we know almost nothing about her past after all, but because Abrams decided to leave that a mystery to be trickled to the audience in later installments, it hurt the character in this movie.
