I enjoyed it...though I didn't agree with him saying that horses can't be bribed. I have used food as bribery for training horses and never has it had a negative effect. Most animals are food motivated...and some humans I also don't think it's necessary to use bits on horses if you have a good relationship with them and they are trained well.
Any form of training that doesn't cause stress to the horse can't be a bad thing. The stupid woman with 18 stallions annoyed me though. Her horse had to be pts because it was so dangerous.
