"Days of Future Past" is one of the greatest X-Men stories ever. The concept of a time-traveler from a bleak future venturing to the past was a fresh idea at the time, as beaten into the ground as it's become now. Still, there's a reason why pop culture keeps going back to it: when done correctly, it works. Look no further than the X-Men film based on this very title.
This is a write-up I have been looking forward to since I started this blog. With no reservations I can tell you that "The Dark Phoenix Saga" is my favourite comic book story of all time, one of my favourite stories of all time and my pick as the greatest in the history of its medium.
