Well, not me personally, as I do not have any business with the devious & dangerous cult of Scientology myself, other than having lost a member of my extended family to its following. But you'll have to see the BBC's excellent eponymous documentary which tracks the unpleasant experience of the Beeb's John Sweeney when approaching Scientology critically. Up until now, I thought that, surely, urban lore about the cult's nature is overdone, but now I think it's even worse! Have a look at the list of celebrities associated with Scientology - I'll avoid their work going forward.
You can also watch the documentary in three installments on Youtube.
