Sometimes I watch a 1940s film, like the Big Sleep, with motion flow on, and the live video look transforms the film into very present event. Like Bogart and Bacall are on live. The motion flow transforms the chemical emulsion of the past into a live feed in HD and it kind of makes the dead live. Kind of a trip.
Still, I agree, that I prefer to watch cinema in 24p without motion flow.
Writer of the uber-noir Taxi Driver, Paul Schrader, wrote a seminal essay on this question.http://isites.harvard.edu/fs/docs/icb.topic1069028.files/Schrader%20on%2...
Lucas has been at odds with the studios since the beginning of his career. He's very artfully played them and not the other way around. He's a very successful Rebel and remained independent his entire career, in spite of the studio system. In fact Lucas was part of the force that changed the System. He never had to suffer under studio demands and indeed in founded ILM stayed out of reach. That may have been a bad thing for the Prequels as there was no one to reel in his bad ideas.
OTH Nolan started out Indie with Following and Momento and I'd argue has gotten worse by proving he could bring in the Big Budget flix. IMHO often
a small budget leads to more creative filmmaking.
