Two words: Marvel Noir.
... Actually, I don't know if it should be a guilty pleasure, because it's not bad so much as it is polarizing, particularly regarding Wolverine/Daredevil. My truly guilty pleasure would either be the Bible or Flan, but I think Flan is truly good and its content is the only thing making me call it a guilty pleasure because I don't want to come off as a homicidal maniac...
I don't really have any guilty pleasures, I don't think. If I like a book, I like it, imho.
