Saw it yesterday. Even with all the PC/ diversity/ feministic/ liberal crap that Disney injects into every one of it's movies, I still found it enjoyable and better than any of the prequels.
Harrison can still pull it off, but Carrie Fisher (even with the weight loss) looked bad/old from years of smoking, drugs and booze. Her voice has been greatly affected too.
When I saw the previews it seemed like the Hebrew would not fit into the story, but he was actually pretty good.
The villains were there, but nowhere near at intimidating as Vader and the Emperor were.
Don't blink or you might miss Mark Hamill.
My Star Wars nerd rating = 8/10 stars.
