Since I'm a Heinlein fan, I guess I'll settle for being one of the great unwashed. (wink and a smile)
I went a step further. There are at least 19 science fiction or fantasy novels I recognized in the readers' list and only one in the critics' list. (Clockwork Orange, which is science fiction mostly in setting.)
Interesting that the critics' have such little interest in an entire genre that means so much to so many readers.
BTW, I thought it was neat that Heinlein's top-rated book was The Moon is a Harsh Mistress. It's my personal favorite, too.
