Watching this show and some others, Idol for example, it does make me appreciate the talent some people have to deliver original commentary in a short time span and not sound repetitive or bland or ridiculous. I don't think that this is something very many people have and while I think the musicality (if that's the right word) of these 4 judges is clearly there the ability to convey something meaningful quickly and succinctly isn't so much in their wheelhouse as it were. But I also think it doesn't so much matter what they say. These judges aren't instructors at the Juilliard School. I suppose their main task, at least during the actual shows, is to be pleasant and supportive and keep the show moving. Presumably a little more technical advice and constructive instruction goes on behind the scenes.
