Er ... I'm not all that fond of them.
Generally my reaction to them is something like "ok ... but why did we need to hear that? I mean, really. Why? Are you trying to point out some sort of theme I should be looking out for? You think I can't spot it for myself? You haven't even started and you're trying to tell us stuff. I don't want to hear what you have to say yet. Or even what you would like to point out that other people have said. I don't believe in you as an author yet. Sorry. But there it is. Maybe a chapter or so in, I will, but just now, no. Like I said, I'm sorry. It's nothing personal. The rule applies to everyone."
THere's probably an articulate way of summing that up.
