Listening to a podcast today about Shawshank, and they were talking about the movies that were up for Best Picture that year - Quiz Show, Shawshank, Forrest Gump, Pulp Fiction. They brought up a good point that we need a lot more of that - movies that are interested in telling a great story. Now it's largely just a land grab for any known property or franchise so they can guarantee butts in seats at the theater. Just like somebody said about news in another thread, this is our fault - at some point we decided that we want to pay for this junk at the theater, so that is what is being pumped out to a large extent.
I guess I don't know how to answer what are good movies for "smart" people to watch. There are movies of all sorts still out there to find.
