I honestly don't think you need special permission to talk about art. As for disagreeing with their reviews, de gustibus non est disputandum, I always say.

Y'know what? I'm not even going to answer the question. What I will say instead is: read the first few chapters (http://www.princeton.edu/~batke/moby/) and see if you like it. It's really pretty clever, and if the style works for you it'd probably be a good read. And if it doesn't, I won't make you do any (more) slogging - that's your choice entirely.
