That's fine; keep doing what you enjoy. But there is life-changing fiction, so it is not as though there is nothing a person could choose to read that would be great.
They can be good or great entertainment, but that's not what is generally meant when educated people say that a book is great literature. The artistic value of a book is almost independent of how entertaining it might be.
(I say "almost independent" because people who care about the "deeper meaning" get great pleasure from taking their time to discover it.)
Although, sometimes I read those and enjoy them, mostly in an airport. No harm done.
Dr. Seuss's "Oh, the places you'll go" could be read by one person as just a whimsical children's tale. Someone else, though, might see it as an interesting allegory on the journeys that a person might face in their own life.
Likewise, I might look at a squirrel burying nuts in the ground, and see just a squirrel. But a buddhist monk might derive some great wisdom from watching the very same thing.
