This was pretty much another character becomes a god episode. I would say it was average.
The only difference here is that the human character doesn't turn insane and try to take over the ship or kill everyone like Gary Mitchell and Charles Evans did.
I still don't think the writers realized the chemistry that De Lancie and Stewart had with each other yet, and the nice contrast they had to each other as characters, the trained diplomat and the childish god like being. They didn't really start focusing on it until the next Q episode.
