I just binged ALL episodes- as enthralling, educating, and entertaining! Robin reminds me of my childhood presenters on British telly (TV) he's a hybrid of Fred Dineage (HOW) and Chris Tarrant (Tiswas) trust me that's a great compliment- KEEP making these captivating classes The Defiant channels PLEASE. - Just BRILLIANT.
