"Reading Rainbow," which ran on PBS from 1983 until 2006, is remembered with love in a new documentary, "Butterfly in the Sky." Kevin Makin reviews it for @csmonitor. "Ultimately, the documentary is more of a triumph than a requiem. Aside from its praise of programming that advocates for literacy and of [LeVar] Burton himself, there’s a sense of humanity that perseveres and goes beyond the warmness of nostalgia. Maybe it’s watching the smiling kids who became loving adults. Or it could be watching the series’ founders speak about familial ties that went beyond educational rhetoric," he writes.
