Yes I forgot about it! I'm not a big comics fan but I've always loved DC superheroes from the animated series and toys growing up ;).
I've only read (and loved) Watchmen, Batman Year One, The Dark Knight, All Star Superman, The Killing Joke, Kingdom Come and Arkham Asylum: A Serious House on Serious Earth.
Any suggestions? Especially anything starring J'onn J'onzz ;)
