I really can't see why anyone thinks ROTS is any better than the other two. It has all the same weaknesses and even makes some new mistakes. There is a few decent scenes, as in the others. I guess at least this one focuses on the core plot instead of useless side-issues, but even then it wastes time on the wookie world and blah blah.
Let em go. There might be some individual pieces that are OK cinema, but collectively just some dumb movies to be forgotten.
