ROTS is a not a well made movie, it is just a series of cuts and edits that doesn't develop any scene in any fashion, but it is just a greatest hits checklist of all the stuff we wanted to see since 1983. Just think of all things we wanted to see before the PT came out in 1999:
-The duel
-The turn
-The building of Darth Vader
-The force ghost issue
-The extinction of the jedi
-The birth of the twins and where they end up at
-Yoda vs The Emperor
-The rise of the Empire
THIS IS ALL IN THE LAST HOUR OF THE MOVIE!!!!!!!!!!!!!!!!!!!!!! So in a sense, it is pretty entertaining cause it is the pure redmeat of the PT, yet it is laughable, cause it is executed so poorly from a movie making point of view. I will stand by this statement that ROTS SHOULD HAVE BEEN THE PT!! ROTS should have been all 3 movies, with certain plot points from TPM/AOTC, and the ROTS story should have been fleshed out to 6 hours instead of the last hour.
Trust me, the ROTS lovers love the plot points that are in the movie no matter how Lucas made, they don't love the movie. There was nothing ingenious about showing Leia flying to Alderran and being held by Mother & Father Organa, anyone of us could have filmed that scene, the movie is loved for its images, not the quality.
