The disconnect between Young Lucas and Old Lucas is simply ludicrous at this point (and I'm not talking about the waistline & fourth chin). I simply can't believe that the nerdy guy fascinated by the cerebral aspect of motion pictures (as seen in 'Maker of Films') would turn into such a clueless hack.
When I was young, and listened to Yoda's warnings about the dangers of the dark side (quicker, easier, more seductive), I wondered what kinds of adult lessons he was referring to. And now I know. "Once you start down the dark path, forever will it dominate your destiny" indeed.
