I don't bother with stuff that's "mostly villains." I like stories about nice people. Who are reasonably intelligent. So thank you for alerting me about Vile Bodies; I'm sure I'd find the whole book pretty vile.However, if I'm going to read something with mostly villains, I need to be reading something else with pretty good characters.
Probably why Seinfeld never appealed to me, and why the one time I saw an episode of Curb Your Enthusiasm, I had none to curb. And why soap operas are something I go out of my way to avoid.
