Scott hasn't seen Star Wars: The Force Awakens yet, but he has heard nothing but good things. It seems that most people are writing reviews just saying that they like it, and not giving any plot details. Leo says that it's on track to be the highest grossing opening film of all time. As for 3D, there's really nothing in the movie that takes advantage of it. It was largely invisible. Scott says that's why he's going to see it at the El Capitan in Dolby Vision with Dolby Cinema High Dynamic Range.
Scott says that being shot in film, it naturally has high dynamic range. The question is, was that HDR lost in the scanning? You have to scan the image in with a scanner that supports HDR, and the 10 theaters that have HDR - including one in LA - will have an amazing picture. Leo also likes that The Force Awakens had far more practical effects, rather than over relying on CGI.
