Just caught up with the series this week, I quite enjoy them, it does give you an insight into how football clubs are run. To be an owner I think you have to have a degree of megalomania, as you are a fan and want success, will just depend on how patient owners are.
Have watched most of these fly on the wall documentaries including the Sunderland, Man City, and Crystal Palace ones. Palace one for me was most insightful as it started with their court case (in 2010?), and charted their rise to the Prem.
