Ok, I will clarify... intellectually, the seminar did not have enough "meat" for me. I stand by that, although I did learn a few things. But emotionally, it's a big motivation. Farshteist du dem chiluk?
My 10 year old understood when I told him the rules, 15 and over. Honestly, I think he would have loved it, but it's okay, you can't give kids everything they want. Like the Rebbe Rashab used to lock the temimim out sometimes during a maamar so that they would have to strain to listen at the door. :-)
And I'll say once again, the point of these seminars is a bekiyos/girsa style to show the incredible breadth of what is possible. And hopefully inspire people to dig deeper and leave their misconceptions behind. 99.9% of people learn something new.
It sounds like you were looking for a deep iyun shiur. Like I said I can spend hours on any of the the 128 slides in the powerpoint. But the market for that is tiny and everyone would want it given on a different slide.
So unless I'm opening a mileage university with 128 different courses I don't see how it would be feasible.
