This is the only “series” of movies we have on our list. We simply couldn’t determine which specific movie was the best. It gets even more difficult if you keep in consideration the newer spinoffs such as the Wolverine movie. The X-men movies have something for everyone whether it be super strength, dangerous weapons or even physiological powers. X-men in our minds has always been the best of all worlds when it comes to superhero excitement. I imagine as the series continues to develop it will only continue to rise in our list of top 5 superhero movies.
