Ironic that after the onslaught of CGI, "real" feels like a special effect. Thank you Chris Nolan for taking the time and effort to wow us with good old-fashioned "movie magic." The best, most convincing parts of the film feel more real because they are more real. No debate here as to whether the zero gravity is "photo realistic". Go and support an ingenious, creatively written, beautifully acted, brilliantly directed movie. And be prepared to be awed.
