Yet another Dark Knight Rises trailer has come out, making me want to watch the movie no less than every other trailer that has come out for the movie. At some point the studio needs to figure out what’s cost effective. I was ready to see the movie after the first trailer. Not only that but I really really wanted to see the movie after the first trailer. After the second, I wanted to see it even more. They sold me, when the movie came out, I was going to go see it. After three, four, and five, nothing has changed. I am still going to see the movie. I’m sure it doesnt cost that much to make these trailers but at some point the value added has to be pretty diminished..
