There are any number of minefields into which “Goodbye Christopher Robin” might easily have wandered — it’s a fall-release biopic set in England between the wars, about the creation of a beloved classic of children’s literature — but the film emerges mostly unscathed as neither a hagiography nor a hatchet job on A.A. Milne, the creator of Winnie the Pooh.
Or at least the co-creator: The film posits that Milne’s young son assembled the characters (from his collection of stuffed animals) and wandered with them through the nearby woods while dad, in a rare spate of attentiveness, took a lot of notes.
