Goodbye Christopher Robin tells the story of writer AA Milne, the creator of Winnie the Pooh, and his son, the real life Christopher Robin.
The film specifically focuses on the time period between the two World Wars. In the beginning we see Milne, a writer, trying to return to a normal life after participating in World War I, the psychological effects of the War still tormenting him frequently, and even things like the sound of a bursting balloon throwing him into pain. He finds himself unable to come back to writing. The film later shows how Milne connects with his son, building characters, stories and a whole world surrounding the boy's stuffed toy animals.
The World of Winnie the Pooh and his friends was meant to be a private family thing for the child, but soon, Milne publishes books on those stories, and Christopher Robin, who features as a main character in the book, becomes immensely popular. The film attempts to show how such a public attention affected Christopher Robin's childhood, and how he felt a bit lonely and betrayed during his childhood in spite of being projected as a happy child in those stories, living in the "Hundred Acre Wood".
I felt that Goodbye Christopher Robin had a great theme, and a much superior movie could have been made based on the theme. The film is still a good attempt, with some very touching moments, great camera works, and some good music.
