I am actually quite happy Hamilton did not win scenic design, as there is nothing special or unique about its set. Its simply a brick wall, with a wooden staircase and platform. Many Off-Broadway transfer's sets athough simplistic are also sybolic. Once's mirrior (which i detested, but they meant something), Spring Awakening (the duality between 19th century germany and the present), and Next to Normal (Diana's mind). Hamilton's set was created out of pure functionality, which is not a bad thing, but when you have inventive and ornate sets like She Loves Me, American Psycho, and Shuffle Along, it should not be recognized.
I also don't think it should have won Best Costume Design should have gone to On Your Feet!, American Psycho, or Shuffle Along, but 2 of the 3 weren't nominated. There were no fantastical/ornate that "Screamed" costumes this year though like Cinderella, Kinky Boots, Shrek, Beauty and the Beast, and Pircilla Queen of the Desert.
