It's not bad. I'm on episode two and I do like all their character choices. I do kind of wish there was a Fred cologne and a knobs knobs as the comedic relief instead of kind of making Sam Vimes a little quirky but that might change as the season goes on. I do like the feel of the city being a little more technologically advanced while still having the explanations for it in the show. overall I hope they stayed more true to who each character is in the book but keep the same actors. I would love to see a fifth elephant plot line in future seasons.
