300 was the graphic novel that did it for me for graphic novels.

Any genre that can take a tale as gripping as the Persian invasion of Greece, and make it quite as childish and tedious as 300 did, deseves to be expunged from the culture. There was more depth in a Commando war comic. Heck, there was more depth in me and my mates playing wargames in the school playground in the 70s.

I'll save anyone the bother of reading 300 by summarising the entire book here: "Spartans !!! Dems well 'ard, innit."

Still, given that the book was the pits, we may have a first, a film adaptation of a graphic novel that is actually an improvement.
