Well, one key element is a character who refuses to grow up, just like Peter Pan. There's also usually a magical or fantastical setting, like Neverland. And there are often friends or sidekicks that accompany the main character on their adventures.
By using modern settings. For example, instead of a magical island, it could be a virtual reality world. Modern day problems can also be incorporated, like social media stress.
Peter Pan is in love with Wendy. Wendy's arrival in Neverland changes things for Peter. She brings a sense of warmth and home - like feeling. Peter is drawn to her because she has qualities that are lacking in Neverland. She can cook, tell stories, and provide a nurturing presence. Peter's love for Wendy is shown through his eagerness to have her stay in Neverland and be part of his world, although he doesn't fully understand the nature of adult - like love.
Peter Pan doesn't really have a traditional romantic love story in the classic sense. He has a special relationship with Wendy. Wendy is like a mother figure and a friend to Peter. He enjoys her company and they go on adventures together in Neverland. But it's not a typical grown - up love. It's more of a childish, innocent bond.
The story is set mainly in Neverland, a magical island full of pirates, fairies, mermaids and lost boys. It also has some parts set in London, where the Darling family lives.
Peter Pan can be interpreted as a sad story depending on your perspective. The lost boys' search for a home and Wendy's eventual return to the real world might make you feel a bit melancholic.
Yes, in some ways it can be considered dark. There are elements of lost childhood, abandonment, and the constant struggle between imagination and reality.
