While I'm a complete sucker for every Disney movie ever made, I remember bawling uncontrollably when I saw Dumbo for the first time as a kid. I was a pile of tears, and planned according by bringing a box of tissues to the screening.
For example, as soon as the stork drops off Dumbo to his mom in the original film — a plot point which is omitted in the remake — Mrs. Jumbo is quickly deemed crazy after she attacks a pack of unruly boys who were tormenting her baby. While the pair are still separated in the 2019 film, Dumbo has a support system to lean on, making the scene a little more bearable. The storyline certainly starts out glum, but it's nothing kids can't handle. Phew!
