It’s good right up until the last two books or so (thinking specifically of Snuff, but also Raising Steam here), where Vimes becomes a complete parody of himself, and there is also a large drop in quality.
Maybe Pratchett’s disease had something to do with it.
It’s OK though, they offered their top moderators an offer to participate in the IPO and also sent them goodies and snacks, what more do you want ?
