I'm not at all cocerned about this sensei being brutal or not.
Technically speaking he has few enourmous fails.
He keeps looking to the floor were my sensei always correct me with: Look up there's nothing on the floor!
He has open and tensed fingers (very tensed) wich for the fans of the "fight" will result in the uke to go for a finger rather theb the wrist.
He's working always on a line and frontal to the uke.
