I can't speak to the "fun" aspect, however I lost all interest in this particular youtube channel after viewing its video about the Apollo Hasselblads. I don't consider myself any sort of expert, at all, about those, even if I have read the NASA reports about photography during the Mercury, Gemini and Apollo programs. Yet, I quickly noted various factual inaccuracies throughout. If I need to learn more than I already know about the 70 millimetre Graflex camera at some point, I will seek out reliable sources of information.
