What did I think? I was very much in two minds about it. As a film it was good, well produced, good casting, interesting female lead, good action, good effects, pretty much seamless CGI. Also I was pleasantly surprised that Disney hadn't Disney-fied it, in fact it was a lot less whimsical than most of Lucas's efforts. Also the Storm troopers finally seem to have learned to hit something with a blaster.
However, as a continuation of the Star Wars series (and I've watched them all at the Cinema) I thought it was pretty much a rehash of the other films without being a full-on "reboot" (e.g. Batman). How many times are the baddies going to build a mega weapon only for it to be defeated by a handful of X-Wings? How many force-users are going to kill their farthers? Why did the supreme leader look like Gollum? Could Rey really teach herself to use the force to that extent (the force is strong in this one, indeed), if so why did Luke need so much help (probably because he is a bloke...)
And they just couldn't get away from the stock Hollywood clichés with respect to the black supporting actor.
So overall I enjoyed the film, and thought it was worth watching in it's own right but I was bit underwhelmed by it as the next episode of Star Wars, although that is probably true of every Star Wars film apart from the first two, so may be it is keeping up a fine tradition.
