You’ve been warned!
In the book, Wen dies. Cast lists a character as “adult Wen.” Assuming in order of appearance, she is shown at the end. What do we think? Imagining a potential future that will never be? Or she lives in the movie? Seemed like in the trailer Leonard was carrying her body. M Night Shaymalan loves a good twist! I just hope it’s not open-ended. I hated that about the book.
The featured Imdb review mentions the ending changes for the worse.

The ending of the film is not open-ended like the book is. Full disclosure, I'm not a fan of the book, but I really appreciate what Shyamalan did here.
Fans of the book might be disappointed, because it changes the tone completely. I honestly appreciate the revision, and quite frankly, it's really consistent with some of the themes he often employs (Unbreakable, Signs, etc.)
That said, I'm not confirming what you wrote or not, in case you didn't want to be spoiled.
