So Bryan Lee O’Malley is the creator of Scott Pilgrim. Scott Pilgrim, before it was an awesome movie that nobody but a few people and some critics watched, is a manga. It's sister manga, Lost at Sea, was written by O’Malley prior to the first novel of Scott Pilgrim. I've read both. I consider them both excellent examples of how visual medium and text medium can be combined to write meaningful and entertaining stories. But don't just take my word for it:
Before ‘Scott Pilgrim,’ a Girl Adrift By Jennifer B. McDonald (New York Times Review) Pilgrim’s Progress By Charles Yu (New York Times Review) For my female friends who managed to see the movie but not read the manga, who took except at the lack of dynamic female characters, I highly suggest reading the first link by Jennifer McDonald, in order to get a better feel for how the source material portrayed the female characters of Scott Pilgrim before they went through Hollywood filtering.
Anyway again I highly suggest both series. For my friends, I might be willing to loan out copies. Also note that Bryan has announced on his blog that a box set of Scott Pilgrim with fancy new art box and a poster will be released in the new future. Le sigh... sometimes being a fan costs way too much money.
