The screw up with the celeb caller hanging up on Tamori was pretty good with all the girls laughing their heads off.
I would say Tamori is at his best with one on one interviews, or at least compared to Sanma when he has a group on.
But Tamori is like a kindly grandfather interested in his guests's thoughts, whereas Sanma is a bit of a lecherous Uncle, who likes to party with the guests. Plus Sanma has the comfortable set with the couches, whereas Tamori has the front row, back row set up. Frankly, perching on those stools in the back row is not a very relaxing place to sit, and the people sitting in the lower chairs up front always have an advantage.
I don't mind the older girls taking the lead on these shows, because they tend to know a lot more people in show biz, and they can keep up with the hosts. When the younger girls just get a moment or two in, it leaves the viewer with a good impression, wanting to see more of that girl the next time you see her on television. Such as Kudo saying thanks to the audience when some of the ladies were "kawaii"-ing her. A quick nod and thank you by Kudo was charming and natural, rather than trying to force funny comments.
