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.

And You Thought It Would Fail: Michael Eisner, CEO of Disney, stated publicly that he thought Pixar would be taken down a peg by this film's probable failure. Instead, the film became a megasmash hit that outgrossed The Lion King which happened at the worst possible time for him in not only undermining his reputation for his skill in the entertainment business, but it also came out near the end of Disney's contract with Pixar, putting the studio in a position of unassailable strength after a string of five consecutive blockbuster hits and owned by Steve Jobs, who loathed Eisner. At this threat of this movie powerhouse going to their competitors, the Board of Directors got rid of Eisner in part to placate Jobs.
Strawman Has a Point: Some who were involved with the production have said that Eisner's comments were understandable given the rough first cut he viewed, which had the fate of Nemo's mother and siblings revealed over time in flashbacksnote In the film's commentary, Andrew Stanton said they eventually nixed this as by the time the reveal happened, the audience would've already figured it out, and that by starting with the barracuda attack, you immediately know the attachment between Marlin and Nemo, and why Marlin was overprotective, Gill was a more untrustworthy character that unnecessarily muddled up the second act, and William H. Macy was voicing Marlinnote Stanton: "Albert Brooks. He absolutely saved this picture. He is exactly what I needed this father character to be. You needed someone who was neurotic, over-protective but still appealing throughout. And that is one of Albert's gifts. That he can sort of play both. Usually it's such an off-putting thing. But he just makes it so winning." Of course, the undercurrent of Eisner's comments was that he was rooting for the film to flop so he could have the leverage in negotiations, but the film, like Toy Story before it, needed to undergo changes before it became the universally beloved film everyone knows.
Asexual: Dory, at least conceivably. Never shows any romantic attraction to any other character, and seems to live in a world all of her own.
"First you were like "Whoa!," and we were like "WHOA!" , then you were like "Whoa...."
The Internet delights in making the film sound like a horror film: "An optimistic young family is brutally attacked by a serial killer. The mother is murdered and eaten, along with all her children, the father is traumatized, and their only remaining son is physically disabled. Years later, that son is kidnapped and his father must track him down with the help of a mentally disabled woman."
Almost even more memetic, pointing out that Clownfish are sequential hermaphrodites and reproduce with their family members in time of emergency.
After the 3D re-release, a new meme was sprouted: Marlin appearing randomly screaming "HAVE YOU SEEN MY SON??" in various pictures and other movies.
The DVD commentary said that the take they used was her second one - by the end of recording the first one, she was crying so much because she thought she had ruined the line, and she had to take a break. By the second try, she was still distraught over the first take. An example of accidental method acting.
What Do You Mean, It's for Kids?: Slaughter in the first five minutes, harsh reminders about the true nature of an ocean ecology (i.e. brutal and unforgiving), a missing child kidnapped and placed in a small confined space with creatures driven insane by their confinement and isolation, a neurotic father whose traumatic death of his partner scarred him for life, and an amnesiac with modified forms of both anterograde and retrograde amnesia who holds no memory of her identity? Yep. Sounds like a kid's movie. This is one of those rare times when it's not the individual content of the scenes that act as a Parental Bonus but the context and serious subject matter that underlie it when translated to a human perspective.
The Woobie: Nemo, Marlin and Dory. Especially Nemo in the first tank scene.
