It's a tragedy. It rhymes.

Dune is more like his mom manipulated an established religion to place her son as the figurehead to utilize these people for power, and they eventually fight a holy war in his name

Nah. Dune mostly starts out on a desert planet, and the kid ends up leading a resistance to make a full strike against the current Imperial power structure. And in later episodes of Dune, the boy's visions of the future threaten to send him down a path toward evil, but he chooses to risk everything to save a dear friend...

So it's completely different. /s
