Goodbye Christopher Robin. Quite sentimental, but that was implicit. I only discovered Winnie The Pooh when I was 18, but I rate the stories very highly. There was a bit too much of the And-that's-where-that-came-from stuff. And I do wonder whether mum got a bit scapegoated (but ICBA to read a biography to check). Also, the actor playing little Christopher Robin sometimes looked a bit older than I felt he should, but it's pretty hard to get little kids to act. Not impossible, but hard.
However, I thought the story was well told and the parts really well acted. If you like the stories, and don't mind a bit of a cry, it's a good way to spend 90 mins.
Oh, and I saw it at the Electric Cinema in Brum - the oldest working cinema in the country, they say. It was lovely. Old, a bit shabby, but clean and comfortable and nicely non-corporate. The ads, including trailers, were less than 15 mins. Also recommended.
