I have an unrepentant love of dystopian stories. I think it's an amazing vehicle to delve into men's psyche, especially when you look at the societies created. I also don't believe in utopia (someone's utopia is always someone else's dystopia).
This anthology is a great collection of different dystopias focusing on different issues. There are newer and older stories. Some of them look at man's (in)humanity, some look at totalitarian issues and how they can be implemented, and some look at the whole.
It's a great set, and it's organized thematically, which is fantastic.
Anything that includes Le Guin's "The Ones That Walk Away from Omelas" is always a win. If that story doesn't punch you in the gut, you're dead inside.
I will say, though, that I think the "choose your own adventure" story was my favorite, just out of childhood glee.
