Pretty good overall. Really liked how the story line fixed a major 'plot hole' that carried on for years. Had a great feel to it which tied in to the older movies and the ending leading into a New Hope was fantastic.
Onto the dislikes - I really didn't dig the CGI. It was done well, but I just don't think it's at the stage yet to blend seamlessly amongst humans. Could've had more in the shadows, as holograms or side views to sell it better. It would've been perfectly fine if you had only seen the back of Leia at the end.
I have to admit to not really feeling an investment in the characters either. I found them all a bit cliched and 'meh' - and could barely remember their names. Definitely preferred the newer characters in TFA.
Loved Vaders final scene, hated his first scene. Way too much dialogue that could've been shortened with 'give me an update' then force choking Ben Mendholsens character and ending with 'pray you don't fail me again' or something similar.
So a mixed bag for me - some good stuff, and some things that could have been done better. 7/10.
