G'day, short time reader, first time poster.
Forgive me if my first post is a little disjointed, it's late and I've just finished work (and I've had a couple of relaxing bevvies).
I enjoyed Snuff. It wasn't the best Discworld book and I don't think it's the worst. Having said that, I don't think there is a worst book. I like all the Discworld books so far written, certainly some more than others and some less so than others, but all books I've ejoyed even for simple reasons.
People have gone on about the changes in characters or the 'out of character behaviour of ....' whatever character.
Lets start with Vetinari. People say it's out of character for Vetinari to behave the way he did with regards to the crossword. Why? We've never really encountered any person who's actually managed to vex the Patrician so how are we to know how he acts? And it's not like he behaves in any outragous manner. At first he "uncharacteristically" laughs out loud, Mr Pratchett even acknowledges it's uncharateristic. Also, "... was close to ranting" But someone would have needed to know him very well to realize this (perhaps only Drumknott). What was he doing?? He was drumming his fingers on the table.
Continuing with Vetinari, he is a changed person from when he appeared in Guards Guards. Can you think of a time when Vetinari would have ever reacted to any news by putting his hand over his eyes? Not the usual stoic behaviour of the Patrician but that's the type of behaviour he displayed in Guards Guards. He even paces up and down when worried and snaps at Lupine Wonse. In fact, in Guards Guards you could say that Vetinari is more animated in behaviour than in any other book he's appeared in.
Sybil. Now Sybil barely manages to make an appearance in many of the earlier books yet people seem to know how she would behave (I'm refering to her use of the word bitch). She features a bit in Guards Guard, very little in Men At Arms, Feet of Clay or Jingo. We've seen her scared, worried, upset but have we really seen her cross / angry. I don't think it is out of character for her to use the word bitch. As another poster said, Vimes has rubbed off on her and as she herself stated, she hates the fact that all the other aristocracy thinks she is like them. As other posters have stated also, she's been more fleshed out (sorry if I'm repeating things already posted).
Vimes. Of course Vimes has changed. He's older now, has a son, he's experienced. As raptornx01 put is so excellently, he has learned.
People have also said that the book is too wordy and didn't like the way that everything had to be explained. Have a look at Feet of Clay, the whole confrontation with Vimes and Dragon King of Arms. That whole section is Vimes verbally explaining everything.
Admittedly, I think the whole Summoning Dark thing could have been handled a little better but I don't have a huge problem with it. I think Vimes was willing to listen to it, not necessarily believe it outright, but listen to it to use what it gave him to gain further information. I mean, in Guards Guards we had Gaspode the talking dog telling Angua what happened. I think Vimes is not entirely comfortable having the Summoning Dark with him but he'll use what he has at his disposal at this time. He doesn't like magic being used to solve crimes but the Summoning Dark isn't magic
I loved Willikins in this. I love how he is protective of Young Sam (and of Vimes and Sybil of course). I like how he subtly tells Vimes off for not spending enough time with Young Sam. I did like his confrontation with Stratford, "And you Mister Stratford, set out to kill Commander Vimes's little lad, or worse. And do you know what is even worser? I reckon that if you'd done so, the commander would have arrested you and dragged you to the nearest police station. But inside he'd be cutting himself up because the poor bugger is scared that he could be as bas as you." Brilliant.
There was lots of great scenes in this book like Vimes earning the trust of Tears of the Mushroom by giving her a photo of his son (but I'll spare you going on and on about them all). Yes, this isn't one of Mr Pratchetts best books but I still think it is a good book and really enjoyed it.
And in my opinion, I'd have to say Night Watch is one of the greatest, if not the greatest books I've ever read.
