I sympathize with GL a bit on this one since I would probably have a similar reaction. I write songs and I could totally see myself bitching up a storm if a song I wrote (and that I was really happy with) got tinkered with by my producer or for a radio edit, just because I tend to get really attached to the structure and build-up that I put down. Finding the right momentum and build is like the song telling me that this was the way it was always meant to be, so I totally sympathize with GL reacting in horror to someone fussing with that.
What I really don’t understand is that in the Maker of Films interview GL is acting like they changed the tone of the movie, taking out the humor and the romance. It’s so weird because those qualities are absolutely NOT present in the film. Oh, it does have bits of subtle humor, like the robot cop walking into the wall, or the chase being called off because of budget concerns, but it is absolutely not a warm, romantic movie by any definition. It’s about a world that’s entirely numb and cold, told in a very detached, European fashion. If he really thought those qualities were there…I don’t even know what to say to that, except that it would affirm that, on his own, he has no idea how to make a rousing, romantic, funny, audience-pleasing movie.
