Review: PBS' 'Life of Muhammad' an earnest effort to enlighten

PBS takes on Islam's most revered prophet in an attempt to separate his beliefs from today's extremists.Whether a case of divine intervention or just fortuitous programming, PBS begins airing "The Life of Muhammad," a three-part explanation of the history of Islam, on Tuesday, the same day Al Jazeera America makes its debut on the channel formerly known as Current TV. It's a coincidence that only intensifies the PBS series' air of demystification.
