Okay, I am in the last few books of the Discworld series, in fact I just finished Thud! Over all I love the City Watch (it is one of my favorite series), but in this particular case I felt that the book was a little too Sam-centric for comfort. Yes, Vimes is the heart of the watch, and to add an additional subplot would have added a needless layer on top of what is already a pretty complex structure, but at the same time, given the subject matter and the relevance of dwarf culture and history in this one I would have liked to see a little more of Carrot (and maybe even Cheery) in this one.
I know that doing something like that would have been a fundamental change, and seeing how I like the book, it might well have ended up doing more harm than good (we’ll never know), but it is something that nagged me a bit throughout (as to the question of what could have been cut to make room for such a change, I think a little less time might have been spent in the Nobby Nobbs subplot, and that one of the readings of Where Is My Cow? might have been trimmed a little without inflicting any serious damage).
Oh well, it is still a great read, and seeing it in contrast to the way in which the Discworld as a whole was depicted some thirty books ago is definitely worth it.
