Does what a reader comprehends from a text actually inform you much about the text? Or does it inform you about the reader. If I read a text on the history of oil painting and reached the conclusion that "the color blue was magical and that if you paint yourself blue you will be able to fly and conjure money from thin air" does that really mean anything in relation to the text?

And for the statement that suggests Uncle Tom's Cabin and Clifford are poorly written... I wanted to come up with a point but I can't think of examples. Or maybe I can. If a work references something but we no longer know what it is referencing is that work poorly written? And what about foreshadowing? A work that is part of a larger sequence of work, say Harry Potter, can be looked at in part or in whole. So is it poorly written if each book cannot be entirely comprehended by itself?
