Recently I bought my daughter the latest Tinker Bell movie, The Pirate Fairy. It's a good enough film, and one of the better in the series. The real reason I was excited is that Tom Hiddleston was playing a young version of Captain Hook. If the thought of Loki flying around with tiny winged pirates who use sewing pins as swords doesn't make you smile, then I can't help you.
But it's starting to bother me because there are three current adventure series in Never Land. There's the two proper Peter Pan movies, Tink's films, and Jake and the Never Land Pirates. All three of them are vastly different but take place in the same setting and share characters. I've spent way more time than an adult should trying to figure out how it all fits.
First thing to remember is that fairies and Never Land have an intimate connection to our world, though they are separate. Fairies are born from the laughter of human babies, and I've shown elsewhere how Never Land is more or less created to be the afterlife of dead children.
