Like the project as a whole - not really a fan of their youtube videos - lot's of off the cuff, unscripted, behind the scenes type of stuff. I just want the facts not see what you look like first thing in the morning... I am just waiting for El Doctor to take the camera into the toilet.
But worth a look at, imo
