So if you use this logic then after it dies down a bit and 20 years from now the next crop are going to be giving credit to Singer and Nolan. Basically, it just comes down to who were the influences at the time in their earlier development. Then you have to go back and say, well how do we know some of those involved in Superman the Movie weren't influenced by the Superman TV show from the early 50's, or the Superman serial that played in theaters in the late 40's. The one thing we have from each era of superhero movies are technological advances that bring the same basic original stories back into the forefront because of new and more exciting ways to express them and make them real. Whether it is the capabilities of the 40's/50's, 70's/80's, or just in the last decade. Whether movie serials, TV shows, TV movies, or theatrical movies there has always been an interest because people grew up on the comics and in between the animated series. So the interest has always been there for green lighting such projects. That's why I give credit to the technology more then anything else for breathing new life into the genre from time to time.
