Not to digress even further on the movie end of things, but the sex/violence issue is precisely why Disney started Touchstone Pictures in the 80's. They're just using Fox (a bigger, more well-known name) for that now.
I can see why the Disney brand has to stay clean, I just can't see why 20th Century Fox is any different than DreamWorks and whatever other brand names they have ownership of. If I were Disney, I would want to keep my product separate from the more visible Fox network. Especially since I own ABC.
Like I said, you don't go to the movie theater to watch a movie just because it was mady by Sony. You make that decision on a movie by movie basis based on what the movie is about, the reviews and who the stars are. I don't see it working in the long run.
