These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Naked Sun
Ho Yay: To a surprising degree for a novel published in 1956. Elijah and Daneel have an awfully strong degree of chemistry, especially considering that one of them is a robot. But even Elijah himself is very much conscious of it:
Daneel took Baley's hand and pressed it with firm coolness, his fingers closing to a comfortable but not painful pressure and then releasing it. Baley hoped earnestly that the creature's unreadable eyes could not penetrate Baley's mind and see that wild moment, just past and not yet entirely subsided, when all of Baley had concentrated into a feeling of an intense friendship that was almost love.
