Ah Scott Pilgrim, what a cute, funny, numinously readable little comic you are! Scott's new girlfriend Ramona Flowers has a string of Evil Ex-Boyfriends which Scott must battle if he is to have a relationship with her. Following his first battle in the first book, he has a second battle in the second book (I foresee a third boyfriend battle in book 3 and so on), and the battle plays out like superhero Manga fighters rather than hipster twentysomethings in Canada dossing about which is the rest of the book.
But even if it seems that the characters' pursuits are largely vacuous, and they are, it's still an incredibly fun book that makes you want to keep reading once you've started. Something about Scott Pilgrim's puppy-dog innocence and melodramatic behaviour toward tiny things like his sister knowing his girlfriend casually make him likeable and interesting. Even when he's sitting around playing video games, you don't mind that he does this rather than worry about getting a job to pay rent and whatnot - he's a free spirit but not in an insufferable way.
So yeah the Scott Pilgrim odyssey continues with an excellent second volume and I highly recommend the series thus far as shaping out to be great fun for those looking for a larger than life story drawn in an anime style with lots of humour and some cartoonish violence thrown in.
