What did CS Lewis think didn't reflect God?

Lewis followed Plato's notion of the Forms. He believed everything on Earth reflected the all-perfect, all-joyous God. Or did he? I asked a Christian recently if he thought CS Lewis thought 'all' (books, films, footballs, Frankenstein, Snow White and the Seven Dwarves...even termites or earthworms....EVERYTHING) things reflected God. He said no. But surely this is incorrect? Lewis (I would have thought) felt evil was negation of good, not existing, created forms...Therefore all 'things' cannot be entirely ungodly (in so much as something exists of them!) and, therefore, nothing existing is 'unqualified' to reflect Him?- particularly pleasurable things for He created pleasures... But am I missing something and is there 'something' Lewis would have felt unreflective?
