There is no way to really put your finger on what makes conducting great, even what makes conducting work. Essentially what conducting is about is getting the players to play their best and to be able to use their energy and to access their point of view about the music. There is a connection between the gesture, the physical presence, the aura that a conductor can project, and what the musicians produce.
