The droid being revealed to be a real live prop doesn't surprise me. It certainly did not look like bad CGI to me. I was more like "that's amazing CGI". I think I assumed it was CG since I didn't think they'd be able to pull off the design for real.
That said I still severely dislike the CG falcon, but I'm certain it's just poor CGI as they only finished shooting less than 2 months ago!
Also, is it me or do the name cards have slightly different color grading than the trailer?
