I think @
The Wook wanted from this film what many of us wanted in the mid-'80s after ROTJ -- to see what happened next, to actually
see all the stuff that we didn't get in TFA... Luke setting out to train new Jedi, Leia and Han having to deal with their very different backgrounds and senses of duty, the Rebellion fighting to establish a New Republic while the surviving Empire fought on to preserve itself... All the stuff we had to catch up on now that we're thirty years later.
And, because TFA had to do that as well as introduce the new generation of characters, and all in one film, they kinda did a messy job of it. Some of us can forgive that, and some of us can't. *shrug*
