Anonymity is a wonderful thing if you can hang on to it. I live in Pasadena where we try to keep the movie people out. We discourage them from moving in our neighborhood and if they do we burn effigies on their lawns.
I think it tends to be overused and can be a little bit gimmicky. A lot of people are using 3-D now because they feel have they have to... that will come and go and the pictures that deserve to be in 3-D will continue to be. When it's done bad, it can make you carsick.
