You'll see if you watch the videos, they say something like "this horse has a problem bucking when you cue him to canter" and they tell you the method they'll use to fix it, and show those methods being successfully used, and they'll show the fixed horse. They never show the horse bucking in the first place. They don't look like problem horses to begin with, they seem to use highly trained horses that go through the whole day without breaking headset or losing collection. If that's what they're going to do, they should say "This isn't a problem horse, this horse is just an example of what you're aiming for" There's value in that. I just think there's more value in also showing the bobbles and mistakes. The bobbles and mistakes are part of the scene people have to live through and the videos neglect to show.
They do the same thing in pictures and videos to train horses to load in trailers that have a phobia about trailering. They show the horse all calm, standing there like a saint, and they never show the horse pulling back or kicking at you when you're urging him forward, or sitting back on his butt rope will he falls on his ass.
People who are really having these issues will look at these horses, and their own, and say "Well, yeah - how does that help me? Get "Mine" to do that".
There is a clinician named Chris Cox that will show the actual problem. I have one of his shows copied on Tivo and it's called "stop the bucking". This horse bucked like a booger and they showed it bucking with Chris. It was a riot! I always make a point to watch Chris Cox and I also like Craig Cameron. He'll show the problem horses actually demostrating their problem and it's usually pretty funny.
Monty Roberts, Richard Shrake and especially Dennis Reis are dull as dirt. Pat Parelli is so-so, imho.
