Books you rate low, and you think people should read?

There is something horrible about rating books, in general, and I'd love to have a discussion about that here, but that doesn't matter immediately.

I'm moreso interested on whether there are books you folks have read that you'd rate 1-3 stars, bad to mediocre, that however you think should be read by people by the conversations it starts, the values, the prose, or any reason at all.

For my part, I'm currently slogging through Samuel Delany's Stars in my Pocket, and while I think, so far, I won't rate it above a 3.5, this man prose's is so excessively rich, so abundant, gorgeous and turgid that people should go through the trouble of fighting his awful storytelling.
