I didn't say they were dead. If you keep up with the industry, you'll see that, adjusted for inflation, the new movies aren't selling as many tickets or making as much profit as they did a few years ago. It doesn't help that the movies cost more to make too.
Of course comic book movies are still popular, but eventually everyone will move on to the next big trend. That's just how things go.
EDIT: I'm moving on from this, hoping the thread will get back on topic. If we want to discuss the movies, there's a forum for that.
