The Fourth Wall has been blown up and raped. You'll probably like it.
Yes, ignore how stupid the title is.
Anyway, why is Scott Pilgrim so good?
I don't know. Maybe because of several Chekhov's Guns (that is more like a Chekhov's Arsenal), the destroyed Fourth Wall that keeps being broken, shonen-style fights, shoujo-style relationship, dramedy, or just the simple idea of a 23-year-old nerdy bassist that shares an apartment with his insanely gay and a sex maniac roomate and has his band whose name is a pun on a Mario character and Sex Bomb is surprisingly related to my life somehow.
I think it's all of above.
I can compare it to FLCL. While FLCL is a story of a boy getting out of his childhood and moving to his adolescence, Scott Pilgrim is a story of an adolescent becoming an adult.
Both have the same epicness and craziness effect, but FLCL is wierder, FYI.
On the other hand, for a person that was able to read all 6 books in 4 hours, I may have missed a ton of stuff.
The author seems to have almost all (it's just not all because of Scott and his friend, Lit- I mean Neil) of the secondary (by that I mean reccuring characters) snarky women, bi women, slutty women or gay men.
On short, if you are here, I expect you to be one of the persons who is going to read that and like it a lot.
Otherwise, I may say: "There is someone on TV Tropes
with more than a minimal social life?"
