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.
YMMV: Happy Harmonies
Award Snub: "The Calico Dragon" and "Old Mill Pond" were nominated for the Academy Award, but both predictably lost to Disney shorts of the time.
Awesome Music: "Tales of the Vienna Woods" uses the classic Johann Strauss waltz of the same name, and to memorable effect.
Nightmare Fuel: "Bottles" is a notorious short for it's downright creepy beginning and climax—especially for it's unforgettable villain, a sadistic bottle of poison with a skull and bone arms, that is obsessed with torturing and then trying to kill the poor shopkeeper! And then there's his shrill voice and cackle..
"AH-ha-ha-ha-ha! Death! Walks! Tonight!"
The "Spirits of Ammonia" sent to capture the shopkeeper are also pretty creepy, and they make good on knocking him stiff and handing him over to the heinous poison bottle.
Scenery Porn: The cartoons uniformly have stunningly beautiful background art to go in hand with the lavish animation.
