Re: YouTube: Moriteru Ueshiba Doshu
For me, these types of demos are an odd combination of form, nostalgia and presentation. While not a koryu, aikido often embellishes its connection to a specific historical period of training. It's a demo designed to preach to the choir. In other words, if you are familiar with aikido, the demo is fine. If you are new to aikido, aikido is not a koryu so the pseudo-historical style is off-putting and the lack of a contemporary adversarial relationship is seen as ineffective.
I have said this before, I think takemusu aiki is something that is not easy to communicate in demonstration. It either looks fake or it has to presented to not look fake. Practiced spontaneity.
