I've always thought The Road to Wellville, both the book and the movie, to be underappreciated comedy. There were so many subtle shots at crank health care, in both. One that stands out is Kellogg's forced vegetarian wolf, shivering, drooping, and skin and bones, in a cage. Kellogg claims it's been "tamed".
Oddly enough, it's impossible to find in the used DVD market...
Kellogg was certifiable, but in many ways no different from other Seventh Day Adventist philosophies at the turn of the century. I know this because my great grandfather was a seventh day adventist preacher, and my grandfather told me stories. He didn’t have his first taste of pork until he took a job in a logging camp.
