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: Peace on Earth
Award Snub: This short lost an Academy Award to the Silly Symphonies short "The Ugly Duckling". Thankfully it got better awards later on, it won the Nobel Peace Prize (the only cartoon to ever do so) and is number 40 on Jerry Beck's list of the 50 Greatest Cartoons.
Some Anvils Need to Be Dropped: It certainly took some courage to speak out against war in 1939, though the U.S. being neutral at the time probably helped. A couple of years later, every animation studio would be producing wartime cartoons that glorified war.
