I saw that Martin Jarvis documentary, and any time he made a reasonable claim he'd then immediately pile nonsensical speculation on top. The most egregious statement being that Bach's first wife committed suicide because of a supposed affair between JS and Anna Magdalena.

One of the contributors to the documentary subsequently wrote a rebuttal: http://bachnetwork.co.uk/ub10/ub10-tatlow-wbmb.pdf
