The hero's journey isn't just a lazy reused story structure. It basically has to work this way. If it was erased from existence we would recreate it by necessity.
The hero has to start out normal because
>the viewer relates to them better
>the hero can grow over time
>the viewer can slowly learn about the world as the hero grows and learn things instead of getting infodumped on with exposition
Since the hero starts out normal they need a call to adventure to change things.
Since the hero is normal they have to change to face the challenges of the adventure.
They have to change quickly and get some guidance on what to do, so they have a mentor.
They need some time to grow so they face some challenges along the way.
You need a twist along the way to keep this from getting boring.
The hero is changed by the journey because it would be impossible not to be.
The bad guy is defeated because that's how all stories work (except horror films).
He returns home after the journey because where else would he go?
You can subvert a few of these to keep the viewer on their toes, but not for free.
