You will probably be very disappointed.

Rating: 1/10 (17 December 2015)

It's actually a 1.5 out of 10...
Lame and extremely predictable plot, characters which had almost zero depth, dialog that rarely fits while being rarely fun or witty, and holes in the story big enough to pass a dozen star destroyers flying side-by-side.
This is a review without any spoilers so I cannot go into why the issues exist. (Unless you consider pointing out how bad the movie is to be a spoiler!) I was extremely stunned to see just how bad and predictable this movie was considering the great respect I have for the previous efforts by JJ Abrams. I cannot tell if the issues with the plot or the acting are a result of bad writing or bad directing, but they are bad indeed. It gets a 1.5, simply because it was not as bad as Episode 1. At some point in the future, I would love to rant about all the bad things, but they absolutely would spoil it so I will hold off for at least a few weeks, but you can find references to almost every point I would make in the reviews of others (heck, even in the positive reviews!)
Honestly, the only thing that could have redeemed the movie, even just a bit, would have been to see a certain Gungan, who shall not be named, be decapitated by our new anti-hero in this movie. Unfortunately, we are denied even that small pleasure. They should have adapted the Thrawn trilogy by Timothy Zahn. There is a great story line and one which could have transitioned to the big screen. Go read that series and pretend they count as episodes 7-9. You'll be much happier if you do.
Nobody who is a true Star Wars fan and who actually watched this movie could give this movie a rating any higher than a 5 out of 10, and even that would be extremely charitable.
