Looks like it could be good. For the record, my one sentence review and ratings of the previous films, with links as appropriate to my own site.
Star Wars: Classic, brilliant. 10/10
Empire Strike Back: Best of the series. 10/10
Return of the Jedi: Bit of a letdown, but still fine. 8/10
The Phantom Menace: Has its issues, but I can see the good movie beneath them. 8/10
Attack of the Clones: See above. 8/10
Revenge of the Sith: Best of the prequels, easily, although Williams’ music does about 90% of the emotional heavy lifting. 9/10
The Force Awakens: The new characters are the best part. 9/10
Rogue One: Very different but very good war drama. 9/10
Trailer looks good so far.
