How or why Scott Adams went completely of the rails is perhaps something we'll sadly never understand. Was this opinions he'd always had, but suppressed, did he somehow become radicalized or was it perhaps medically induced, e.g. a stroke or something. It was incredibly sad to see him throw away his life's work and go down a path most of us at least hadn't foreseen and die having alienated his fans.
Another type of work I avoid are "the making of ..." documentaries/accounts of classic works of film, music, and TV shows. Pulling back the curtain really destroys the magic.
