I'll be 31-years-old in a few months, but I still feel like a kid at Christmas whenever a new Batman graphic novel comes out. The stories and artwork keep getting better and better. I love Superman, Justice League, X-men, Hulk, and various other DC and Marvel series, but for me, it always comes back to Batman.
The latest one I finished was Batman: Dead to Rights. It was excellent and a wonderful new take on Batman and the Joker's initial meeting. If you are fan of Batman, you should check it out.
