T>I just think it's the same as with anything, once the big profit makers get involved, they flood the market, often just trying to recreate yesterday's earners. It was the same in the music industry, as my cousin said 'too many accountants'(and not enough talent). But the way people obtained music shifted and the whole industry has to restructure.
The major studios are all about profit and that's why they recreate past hits, with limited scope. But with film makers like Steven Soderbergh making a film on his phone, and laptop effects and editing, more independent film makers can compete. Also with the way people are changing their viewing habits, may affect the studios. Tony Scott did make a couple of music videos at that time; George Michael and Kenny Loggins.
