Great contest - This movie is incredible. If you like 300 try picking up the novel "The Hot Gates" which is based on the same historic battle.
My favorite graphic novel/comic book at the moment is the current Gunslinger Born series of comics based the character Roland Deschain from Steven King's Dark Tower series. It is currently in the middle of a series of 7 issues, but I belevie they will be publsihed in graphic novel form this fall. Excellent series if you are a fan of Dark tower.
