The X-Men where my favorite superheros when I was a teenager (as much as I love The Avengers and each of their individual movies, I found their comics boring). X-Men probably make up a quarter of my comic book collection. In fact, I probably have the original Days of Future Past storyline sealed up downstairs. What's nice to see in this trailer is all of the different X-Men and other mutants from the comics making appearances. Should be fun!
