Yeah, visually like a combination of Narnia and Avatar.100% completely agree. Hyrule needs to be vibrant.
This requires a higher budget. I do hope they put enough money in the film. What a shame if it ended up as those cheap fantasy adventure shows that aired on television in the past. I used to watch one of them but I don't remember the title
(EDIT: it was "Legend of the Seeker")
What about the tone? Adventurous and fantastical, obviously, yet still mature.
Imagine something close to LOTR but with brighter colors and a bit more magic (Jackson held the sorcery somewhat back).
Might as well throw in an amount of Neverending Story in the mix. I suddenly see some similarity between that and Zelda

That last sentence gave me a weird realization. I start to wonder if Zelda and Link could be a little inspired by Child Empress and Atreyu.
