These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ambiguous Disorder: The Duke. He appears to have no real friends and rarely interacts with anyone else in the film aside from Bess or Georgiana. He's cold, distant and admits several times he's not good at expressing his feelings; while the closest he comes to expressing any emotion (other than anger) is when interacting with Bess' sons and his pet dogs.
Award Snub: Keira Knightley, who was praised pretty much universally for her performance, only received a few measly nominations.
