Brad Brevet reviewed Side by Side for Rope of Silicon. He gave an in depth review of the documentary along with several of his own thoughtful comments. one of his commments that struck a cord with me was:
One quote I personally grabbed on to was when George Lucas says he realized with digital, “I can do anything to fix this movie.” I don’t like the idea of a director thinking he can “fix” a film as long as he can manipulate the image alone. This to me suggests a lack of interest and/or focus on story and performance, but I can’t say this comes as a result of digital filmmaking and may simply be a piece of evidence as to what went wrong with the Star Wars prequels.
All in all a good read. Mr. Brevet gave Side by Side an A. The entire review can be read here.
