[KillSmiley]

*SPOILERS*

SunnyD: Here's what I meant: the book Ophelia got from the faun clearly shows the dagger in the middle door. When she's in the Pale Man's chamber, the faeries point to the middle door. But ultimately, she unlocks the left door instead, which seems to be the correct choice. Maybe I'm overthinking it, but I always thought that there had to be some reference there.

Del Toro himself said that he accepts the fairy tale ending, for the same reason that many of the commenters mentioned (the chalk door). Killjoy that I am, I must point out that we never actually see Ophelia escape via the door. There may well be another passage that we aren't seeing. Also, the fairy tale ending doesn't make sense to me because she sees her father, mother and brother, even though her brother is very much alive. Of course, I've always been partial to bittersweet endings.
