Agreed about the overabundance of CG effects. Just because you CAN make a droid roll around on soccer ball, do you HAVE to? And the Millennium Falcon is supposed to be a hot-rodded old freighter that can go very, very fast in a straight line and maybe swerve a bit when in just the right hands. It's not a magical frisbee or a freaking Golden Snitch.
Way back in the Muppet Movie trailer when Kermit the Frog rode a bicycle it was a hilariously funny special effect because you knew that he's supposed to have legs and should be able to do it, but you're surprised and delighted that they somehow pulled it off. In 2015 you can make Han Solo's spaceship do backflips and make a droid race along on a soccer ball but nobody expects it or wants them to, and nobody will spend a single second being amazed.
AND ... I'll be there lined up to see the movie on opening day.
