This is fundamental misunderstanding of literature.

This is like saying to a musician: I like the melody but you chose all the wrong instruments.

Obviously, the entire character of a song depends not only on the melody (idea) but also on the instruments chosen, the performance, etc. (material).

For literary fiction, the words are the material. What distinguishes literary works is not merely the "ideas" they present but the way in which they are presented. The words are the author's instruments, his paints. This is the difference between writing/reading for information and writing/reading as an aesthetic experience. Literary fiction of course imparts information and ideas, but it is predominantly about the latter experience insofar as the point is the evocative expression of those ideas.

This is why just reading the cliff notes for a literary work is missing the point.
