What are some good Superman comics?

[JeremyScheid]

Ever since I was little I never liked Superman. But for the pass few years I started to like him more and more. I'm not sure why. So I want to know what are some good Superman comics. I'm talking about comics or graphic novels that every die heart fan must own. Please list as many as you want.

I like the Superman/Batman series, but that's because I'm a batfan.
