Sequels make $$. Movies are there to make money. For artistic integrity you even have to bypass Sundance and stuff and go to… go to… go to… hm… I guess you can find some artists with integrity buried on Youtube somewhere, or deep in the bowels of some musty University film lab.
I make creative crap (my youtube and other places are filled with it) but I gave on integrity long ago, although I didn’t do it for money. I did it because I just want to see a result from an idea and puke it out here somewhere.
