I love the Monty Python gang, including Terry Jones (Sir Bedivere and many other characters in the Holy Grail), the host of 'Medieval Lives', but some of the Medieval Lives: The Knight episode is a bit one-sided. He presents an interesting argument that knights were nothing but self-interested, fame-seeking, sex-crazed warmongers. Like everything, the truth is usually somewhere between the two extreme points of view
Once he moves past that it gets a lot better.
He does spend a lot of time on the Marshal though
