If you include non-humans, then Stan from Dog with a Blog is the second adult protagonist, albeit a dog.

*Raven's Home stars Raven-Symoné as an adult in-canon, but I'm reluctant to include it since it is a spin-off of Raven's teenage character in That's So Raven.

If you accept movies and works where there is a shared protagonist role, then you could count Freaky Friday and I assume its spin-offs.

I was eating some chocolate when I imagined a world where Hershey's was widely accepted, even by elitists, as the best chocolate.

Is consumer elitism just a facade for pretentious contrarians? Or are there things where even most snobs agree with the masses?

Also, I mean that the product is intrinsically considered to be the best option. I'm not considering social products where the user network makes the experience.

Edit: I was not eating Hershey's. Hershey's being the best chocolate is a bizarro universe in this hypothetical.
