Media by their nature inform and/or entertain, usually a combination of the two. Hard to have one without the other.
The lion has good PR as king of the beasts, but would have a tough time one on one against an elephant, rhino, hippo, crocodille, tiger, cape buffalo, grizzly bear, and several others. True, not all those are in the usual lion realm, but many are.
And naturally, like hyenas, lions are more effective hunting in packs, and that's usually done by all the females in the polygamous pride. Usually the prey is a meaty baby of a toothless species. Predators normally don't fight each other because even the winner might sustain too much damage.
Occasionally turf wars are inevitable, and then the pack fights are interesting too, somewhat like West Side Story. When their alpha male is away, female lions sometimes have a tough time when too many hyenas, led by a female (!), gang up on them. Apparently the larger male lion eventually often returns from his wider roaming and crunches the hyena's female leader.
Gotta be a lot of lessons in that, but I just enjoy the ebb and flow and heroics on the Documentary channel. For us lucky humans at the top of the food chain, that's entertainment, and a lot of information too.
In The Lion King, Disney is just making money on the usual convenient stereotypes. But I think adults are obligated to point out to kids whenever the entertainment and "suspension of disbelief" (to quote some famous critic) need footnoting.
