The problem --and I have to phrase this very carefully -- is that they're not making movies for grown ups anymore. Every movie caters to someone with the IQ of a not terribly bright 16 year old.
Apparently, that's where the money is...MUD
Movie attendees are largely drawn from two groups: (1) Unmarried teenagers and 20-somethings (predominately male); and (2) adults accompanying children. Everyone else waits for the DVDs. Contemporary films are most definitely dumbed down -- compare the LOTR films (dumbed down with more in common with Dungeons and Dragons) with the books they were allegedly made from.
