Some thoughts:
It's a fun movie, but also one with problems - like The Force Awakens, it's not weighed down by Lucas' flaws, but also like TFA, it's not elevated by his genius either.
There are quite a lot of pacing and editing problems, which are to be expected from having such extensive re-shoots, and a lot of bits from the trailers aren't in the final cut.
The late change in composers also makes for a rather rushed and flat score, even weaker than TFA's score.
Lots of fun references to the other movies, and some slightly hit and miss CGI work to bring back a couple of very familiar faces.
Character development is close to zero for most of the cast - it's a larger ensemble than other SW movies, so there's not as much time to flesh out characters, so some of them come off as 2-dimensional even for an SW movie.
The recreation of the style of ANH is very well done, and links up almost seamlessly with the original movie by the end.
Darth Vader is pretty much just a cameo, but his short amount of screen time will very likely still please all fans of the Empire.
The re-shoots affect the tone of the movie, as it seems caught between trying to be a darker and grittier take on the SW universe and fitting in with the tone of the other movies.
