I think his website wouldn't have posted the excerpt if they didn't want us to judge it and decide about purchasing the book accordingly. I like to watch Scooby-Doo, but I don't think I want to read about his adventures in Tamriel.
I have a flawless plan (for once), though. I'm gonna get it at the library. It's a much stronger statement of support or not. If someone reads a 1-chapter blurb, hates it, and dosen't buy it, nothing much is said. If someone reads a 1-chapter blurb, hates it, then buys it anyways, that's just stupid. If someone reads the whole book, hates it, and dosen't buy it (or likes it and does) then that means more. The only way to really show your opinion of something to a corporation is "do you buy their product?" It dosen't matter what you complain about, if you buy a product that you don't like, you're saying that they get money out of it and will continue. (This is not actually directed at Shades, but the general public).
Also we need to remember that Keyes always has several branching groups of characters (and I'm gonna go ahead and assume he'll stay true to form and develop the hell out of Glim and Annaig by the end) so the first chapter is not much indication of the characters in their entirety.
PS: If it is though, I'll be pissed even though I like Glim and Annaig. Character development is a big thing for me, wether or not I like them as they are.
