'Apollo 11' takes nostalgic but chilly flight back in time

"Apollo 11" might focus on the moon mission of a half-century ago, but in its own way the CNN Films documentary feels like a step into a time capsule. Meticulously recapturing the drama of that "giant leap for mankind" in 1969, it's a wonderfully nostalgic if somewhat antiseptic reminder of what it meant to first break the bonds of Earth.
