One thing I'd like, especially when we come back to VoDt, it for the story to remain episodic. One thing that became all too common in 2010's fantasy movies is to try to give a "tighter" plot tread to stories that were either more episodic in nature, like Dawn Treader, or The Hobbit ( as studio Execs argued that it would be hard for "modern kids" to follow if the story stopped and started) , or were more dream-realm like in Tim Burton's Alice in Wonderland or Nutcracker and the Four Realms In an attempt to give Alice and Clara more "agency". This thought actually occurred to me while rewatching Nutcracker and the Four Realms with my 7 year old niece. She abosultly loves the Nutcracker. In fact this Christmas she is dancing as one of the Harlequin dolls in her dance schools production and she hopes to one day be either Clara or the Sugar Plum Fairy. Her biggest complaints during Four Realms were:
"Why doesn't Clara Get the Nutcracker! Fritz shouldn't get it!"
"But Clara loves the Nutcracker! Fritz will just break it!"
"They changed too much of the story!"
"Clara is supposed to fall asleep when this stuff happens!"
and...
"Why did they make Sugar Plum Fairy the Bad guy? She's my favorite!"
"Nu-uh. Rat King cannot be a good guy!"
If a 7 year old girl, your target demo for the Nutcracker, thinks you changed too much and ruined a "pretty" character girls like her love, and made the ugly disgusting character she hates, ( sorry,most girls will ever love the Rat King no matter how sympathetic you try and make him) then perhaps you should rethink your approach to doing the Nutcracker.
Same goes for Narnia. If you take Lewis' words that Aslan is "not safe" to mean he has to be be "more like a villain" in and Jadis needs to be the "true hero" of Narnia, then don't do Narnia.
