I don't know what has happened to movies, but lately every movie is at least 20 minutes too long. It used to be that if you were three hours long it was because it was epic - a movie about Gandhi; something with very important subject matters.
I think that there's a lot more freedom in the low budget, the independent films where, unfortunately, you don't have the money, necessarily, to get the orchestras in there to play a lot of stuff. But, you have a lot more freedom, very often.
