I had to read this for my Open University course, but I really enjoyed it. It's a great story, and there are bits in the book that aren't in any of the film or panto versions I've watched, which makes it something new and interesting even after watching so many other versions.
I've only read Peter Pan, not the other plays, but I loved it. Some of the lines are so moving, like when Wendy asks, "Boy, why are you crying?" I was surprised how touching some of the moments like that were when read with the stage directions.
I think it was watching Finding Neverland that inspired me to read the original play Peter Pan. If you've never bothered to read it, or have only read the novel, I highly recommend it. The stage directions and notes are the best parts, and make for a highly entertaining read. Between the lines and underneath all the silliness, there is a great deal of wit and insight.
(I also read What Every Woman Knows, and felt a bit disappointed at the lack of depth and sensitivity in comparison to Peter Pan.)
I'm in the middle of writing an essay about this and I'm really starting to realize just how well-written and structured this book is! Like I've always liked it, but HONEY. The Disney version does not do this absolutely hilarious and honestly pretty dark book justice. Although upon research I'm starting to think J. M. Barrie might not have been the g r e a t e s t person, this play really is that good. Bumped up from 4 to 5 stars!
For how much I love Peter Pan, I had never read the original play! This is very nearly identical to the novelization of the story, and was kinda surreal to read because it seems that Disney was using this manuscript nearly word for word in the movie version they created. Obviously this was wonderful, though I do prefer the novel to the play just for the fact that I get more enjoyment from a full novel with descriptions and Barrie's beautiful writing than a play (though, it had a lot more writing/stage directions that I thought it would!). Also, this was the first time reading Peter Pan since I read "Little White Bird" and everything is beginning to connect... next I'll be re-reading the novel!
I was quite surprised at how much I disliked the character of Peter Pan - he was really dislikeable and controlling. The gender roles were really annoying as well - Poor child Wendy mothering 9 boys!
