Scary? YES. I noted that after he was "assaulted" from the rear (totally unfair and un-cool) he took a moment to regain and assess after which he slowly and deliberately got planted. Then the robot quickly leaped to his feet. Much like an Arnold Swarzenager or Chuck Norris character.
Apparently the engineers blocked an anger program because instead of a lethal judo kick to the protagonist, the obviously p!ssed off robot simply left the scene.
KEWEL!
