Leftist books, literature, analysis

I ask because I heard that it was a bit liberal. I think one person said that it was "like the American revolution but in space." Which sounds pretty bad to me and, hell, for all I know, it could've been the author him or herself clarifying something to an interviewer. That, and the series is popular and, as weird as this is to most people, when it comes to popular culture and fiction with a huge fandom behind it, I admit that I almost have a negative kneejerk reaction to it; I start to get rather suspicious of it and wonder if it's just another overrated series that everyone is kinda expected to like or at least respect at some level.

Hopefully you get what I'm saying, but either way, I'm bored, and I'm wondering if this series is any good or not.
