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.
Award Snub: Lost to The Artist (another brilliant love letter to cinema in a different sort) for Best Picture.
Conspicuous CG: The gears in the clock tower. While terrifically animated, you can sometimes tell that they aren't real, especially when comparing them to the real things on the sets.
