If Lucas was going to do another trilogy post-ROTJ, it would be more along the lines of the prequels both in story and execution. Unlikable characters, overuse of CGI and issues involving politics. The worst kind of story you can tell is one where something big is brought up (The prophecy of 'the one' who will bring balance to the Force) and we're simply supposed to take the character's word that it's important. Khan having the Genesis Device while on quest for bloody revenge? That's bad. The Force being unbalanced? What the heck are they talking about?
But who knows. Maybe the same thing will happen with the Force Awakens. Someone brings it up, everyone says that the Force has indeed awakened, but it doesn't really matter because nothing about how the Force is used is different at all.
