Actually, the top 6 selling science fiction novels of all time are quite good and have literary cred: 1984 is Numero Uni, followed by the Hunger Games and then each Hunger Games sequel (all three excellent books that are taken seriously), then Animal Farm (of we count that)...and then Dune. Nothing else arguably sci-fi cone close to those 6, and all 6 are legitimately good books by lit-crit lights.But it is also true that there is a lot of best selling genre fiction that is, by literary standards, very, very basic.
