Does that make me a kid?
Seriously, Mulan isn't that close to the original legend/tale, yet, it's considered a classic. Hercules has humour little kids wouldn't understand IMHO. It's same with Emperor's New Groove. I always thought Hera was never Hercules' mom because of her hate for him and the fact Zeus had a habit of ''cheating'' on his wife with various goddesses/humans/things/etc.... Zeus even had a gay lover too. It's true it's not like the actual mythological stories, but THEY'RE not real. Also, there many versions of what happend. None which tell what exactly happend. You could say Disney made their own. One for a suitable audience, not just kids though.
