Aww, i thought it was good, not true to the book but a good story
It was too close and too far from the book for me. For one thing, it was too black/white versus an amusing shade of grey though Vetinari was well written and acted as was Stanley. It was also too romcom focused. Moist did not wind up with a heart of gold in the book but kept his essential nature all the way through which was one of the charms of the book.
Oh well, people are different and obviously tastes are as well.
