Saw it, thought it was pretty good. 3rd act was amazing, some of the best stuff in all of Star Wars IMO, but I felt the movie was downright bad in the second act and just okay in the first. Very little character development, lots of "We're doing this to get these people together and then to go from setpiece A to setpiece B" type moments.
I could see what they were trying to do, but felt the execution wasn't as good as I wanted it to be and the acting was inconsistent.
Over all, I put it behind TFA, ahead of RotS. My movie order goes 5,4,6,TFA,R1,,,3,,,,,1,2.
