From the top of my head…
Plus: The book as a whole… was really good. A lot of the whodunnit I like about some of the Watch books, a lot of Ankh-Morpork-atmosphere (more than in Going Postal, for some reason), suspense and all. When I was at page 199, I had decided I liked it would make it under my top 5, at least for now (its kind of shuffling).

Plus: I really liked most of the new characters introduced, besides finding Sally boring (see below). In Going Postal, I soemhow felt I could connect to the more central newcomers like Moist and “Spike”, but not with the sidekicks in that book. In “Thud”, some of the sidecast is really charismatic, or rather three dimensional I think… Mr Shine, Grag Bashfullson, poor Helmclever, A.E. Pessimal… I loved the small twist with A.E.Pessimal; sent to Vetinari to annoy Vimes (that is what he suspects, at least), and –is simply hired.

I also didn’t expect to see so many well known characters successfully into the story again. All the classic constellations made a re-appearance after having somwhat faded into the background during, say, Night Watch. Nobby and Colon have their scenes, although Colon suddenly displayed a lot of cunningness just when it came handy (the scene in the museum) and fell back into his usual routine later in the museum-related scenes towards the end of the story.
Minus: Sally: for such an eyecatching and charismatic appearance as hers is described to be, she stays surprisingly colourless. Would her character be deleted out of the story, we wouldn’t miss that much, except that putting a vampire into the watch was somehow on the schedule and she was a background to contrast Angua in this book, who was an old regular who got a little more of the spotlight again. We never leran anything more about Sallys oh-so-stunning appearance than that she might pass for 16. I found nothing in the text that enabled me to form some kind of mental picture of her. Maybe I overred something…

Ah, I found it nice to see Angua back, but as she was, as far as I remember, always described as pretty charismatic and all in the Watch books so far, or the type not bothering at all with it, suddenly there’s a big fuss about her feeling like the poor dumb cousin next to, excuse me, a pretty colourless sally-character. She somehow seems to have lost part of her self confidence over her years with Carrot, which is never a good sign for a relationship. I also noticed that all the vampish behaviour Angua saw in Sally, didn’t bother her at all when they combined their effort in “vampish” behaviour when trying to talk Tawnee out of the Nobby-relationship. Was that a Sex-and-the-City reference I only partly got or what? I suspect so...
But I agree to you guys that it would have fit better in earlier Watch books, who were more centred on Ankh Morpork, in a way.

Another thought The curse awfully reminded me of that thing hunting Tiffany in “A Hat Full Of Sky”…. I didn’t mind that, but still – the “its looking for a champion it can use”-bit and all that…
The solution Vimes found for himself –denying that it had succeeded with entering his mind at all –might have fit tha character as such. But even from the most rational person on the disc, you might, seeing that he is a citizen of the Discworld after all, expect some kind of acceptance that such things exist, and are more than folk tale.
That’s it for now. More later.
