The ideas of race and gender don't hold up but the theme of childhood does.

I found it an interesting exercise to read so closely after Tarzan. Both suffer from prominent antiquated attitudes and stereotypes. However Peter Pan fares a little better because those attitudes are less integral to the themes of the work. One imagines (and finds with some of the adaptations) that the most offensive attributes can be worked around, excised somewhat if not completely, without disrupting the power of the story.

The central theme of childhood comes across strongly and skillful. There's a nostalgic feel to reading this as an adult, as though the narration can return you to a younger age. There's a lot to reflect on, from the value, or lack of value, of maturity to the nature of imagination.

It's just a shame to be so often distracted by stereotypes and slurs.
