I think there was sufficient profluence to the novel. This is a thing any story needs. The tradition of having a developed "plot" is the most popular method of satisfying this requirement, but it can also be achieved by gradually solving a riddle or mystery, exploring an idea, or giving a sense of an intriguing setting that is able to imply a rich history of plots and subplots without the narrative directly commenting on any of them.
But on the other hand, a good novel, like a good stand up comedian, should never truly satisfy. You always want to leave them wanting more.
