The Voyage of the Dawn Treade (the Chronicles of Narnia): Simplified Characters

I loved how the Christ-like figure was woven into the story but wondered if the symbolism was more layered here. What do others think about how Lewis used faith themes differently in this installment?

Eustace's character arc felt really impactful, especially his journey from selfishness to bravery. I wonder what led Lewis to emphasize this particular growth in the story.

The islands had such vivid, imaginative descriptions but also a slightly unsettling vibe at times. Did others feel that the fantastical setting added to the sense of adventure or made them uneasy?
