>But what is it that you need to be a good entertainerI don't really know how to describe it. I can only give you a feel for what I mean, its something very general like your personality or enthusiasm.
I could make nitpicks like "They stay quiet for a bit too long" or "they all have this generic bored voice" but I think those are just secondary symptoms to whatever is really going on. If you have the right mindset for this you immediately realize that you need to speak up and generally keep the stream entertaining.
