1. The Death of Superman
One of the best stories that I have ever read in my life.
2. The Reign of Doomsday
So far the storyline is pretty good, just hope it goes out with a bang.
3.For Tommorrow
The darkest storyline ever in the Superman comics where we get to see Superman cut loose.
4.Superman/Batman: Absolute Power
Can you imagine if Superman and Batman ruled the world?
5. Birthright
The first Superman origin story for the 21st century where the kents are young, clark and lex knew each other, and my least favorite the return of bumbling Clark.
