The r/books favorites (for lack of a better name): The Martian and Ready Player One. You could also throw in some other ones that get mentioned a lot, but I think those two are the best examples of the difference between a good book and a bad one. They're both so fucking bland, and a lot of that comes from the fact that they treat world building and nerd service (in the form of gushing about NASA or making terrible references) as a substitute for actual plot and character.
Another example of a weak book (that isn't such an easy target) is Ransom by David Malouf, which retells the story of Priam's embassy to Achilles with some changes. It's a point that sometimes flies under the radar, but a book doesn't just have to be good, but has to have something to make it worth reading as opposed to its competitors. Ransom just horrible fails on that account, because it does absolutely nothing new with Homer's story, and the cost of creating the newer, smaller story is cutting out a lot of the strength of Homer.
