Psychological depth in Tolkien's characters

[Eurytus]

But if person A and person B are both reading the same book and both have the same purpose in mind (eg they want to know the characters as well as they can) and person A gets to know them much better than person B (because he is able to interpret what he is reading) then person A is a more talented reader in that sense.

Or of course, your intepretation could be totally wrong and different from what the author intended.
