As long as it stays in the air, Red Tails is a compelling sky-war pageant of a movie. On the ground, it's a far shakier experience: dutiful and prosaic, with thinly scripted episodes that don't add up to a satisfying story.
There isn't a real, flesh-and-blood figure in the bunch. Everything about Red Tails - the breaking down of racial barriers, the military achievements, the courage and sacrifice - is diminished in the process.
