I just didn't see anything that would make me think that I would be getting anything the would benefit me more than taking an actual course where you practice skills under the tutelage of an instructor/mentor who can correct any mistakes you might make.
If it was something super whiz bang that enabled you to obtain all of the skills required without actually having to take a course it might be interesting. He seems like a fine instructor, and I'm sure taking an actual course with him would be great, but just like Steve Martin's sidemount videos, trying to learn without in-water supervision and direction, whether with an instructor or an adequately experienced mentor, doesn't really get you anything, no matter how much you practica. In fact, it could lead to issues based on a lack of understanding or execution.
The idea that practice makes perfect is bunk. Perfect practice makes perfect. Doesn't matter how much time you spend screwing it up, you're still screwing it up, and you're more likely to continue screwing it up in the future. An online course isn't going to to provide the requisite instruction. In fact, he mentions you need to go see an instructor for guidance, in which case why are you paying for the videos if you're going to go pay an instructor anyway.
