Hmm, this makes me think there's another dividing line as well: those that wanted a continuation of the story of the characters in the PT and OT. I'm personally happy to not see another movie about a Skywalker, so I don't need to see all the off camera action about Luke -- the story presented is consistent with the character in the OT, so that's enough for me. What I want is the handoff from the old characters to the new, and for the story to be about the new characters as much as possible. This means that Luke is a tool of the plot in TLJ, not the focus of it, and I like that. If, instead, you want the see the continuation of the story of the OT characters, I can easily see how this movie disappoints by skipping over a detailed telling of the events in their lives up to this point.
I got the point in TFA that these weren't stories about the OT characters anymore. So, I wasn't disappointed when TLJ didn't spend a lot of time on Luke's story.
