Now that's what I call a movie. It's not world shaking or - apparently - Oscar material. But it is very definitely an enjoyable evening, and I feel so much better for going. Partly, it's just a fascinating, almost unbelievable bit of social history - three black women working at NASA and fighting for recognition in sixties America, all hopeful and Kennedy optimistic, but also stone age in attitudes to gender and race. All that was convincingly done, but not heavily, and the whole thing had an energetic vitality that carried you along - with a lot of help from some marvellous music. This was a feelgood movie in an entirely positive way, and during the credits they showed each of the three main actresses, merging with their real-life equivalents in the sixties, and then shifting forward to their current sparkling old age, triumphant survivors with a stunning story to tell.
