Stranger in a Strange Land

As others have stated, the first half is decent, but it quickly devolves into some sort of sexual revolution utiopian fantasy. The main character starts out vulnerable and interesting but the author quickly starts god-moding him and it becomes tiresome and honestly a little disgusting. The author's vision of the future is twisted in a way that is supposed to be a farcical illustration of the worst in our present society, which seems like it was supposed to be humorous but really came off as miserable and frustrating. It was also supposed to generate disdain in the reader in order to push the reader into being more accepting of the utopian society that is then introduced, but the problem is the utopia doesn't look all that great either, especially since its ultimate fate remains in question at the end. I regret reading this book and I question the wisdom of sticking it out to the end.

A classic. The first half is really interesting, but second half sort of just becomes a 'free love' hippie-commune treatise. It's still worth reading, however.
