I just got back from seeing this, tonight (12/19/15).

And the Force is still strong with this franchise!
I suspect that what most people really found wrong with the Prequel Trilogy is that it had an unhappy ending. But, knowing that the latter was necessary as a prelude to the Original Trilogy, they blamed their dislike (unfairly, in my permanent opinion) on other factors.
Well, I'm just as fairly certain that those complainants will have no reason (or excuse) to dislike the Third Trilogy. For one thing? The heroes of the Original Trilogy are back! Luke Skywalker; Han Solo; Leia; Chewbacca; C3PO; even R2D2. Of course, Disney wisely has their reappearances spread apart, at different intervals. Saving the most dramatic one, for last (though, definitely not least).
Instead, we are given two new heroes to cheer for: Rey (a techno- scavenger on the desert planet Jakku); and FN-1287 aka "Finn" (a stormtrooper-turned-deserter with the proverbial heart of gold). Followed by a proportionately hiss-able villain who calls himself "Kybo Ren." Of course, it soon becomes obvious to the movie-going audience just who and what he really is! A fact that comes as a pleasant surprise to fans (like me) of what used to be known as the Expanded Universe. Because, it dovetails, quite well, with certain elements of the literary New Jedi Order Era even while ret-conning a whole lot of others.
All in all, then, I enjoyed this film so much, I will probably go see it a second time. I can only hope that Episodes Eight and Nine were filmed simultaneously for semi-annual release (the "LOTR Method") as opposed to the three-year cycles of the first two trilogies.
