I loved the first half of the show, especially with guests like Hong Jin Yong, Super Junior, and Kim Min Joon as well, but there were also guests that were rather boring. I admit that as they had to continue shows without audience for the sake of safety, it got a little lackluster, though it was necessary.
I cringed when the show had a teenage fan of Kim Jong Kook wailing on the stage asking him to marry her, and when the Tone-Deaf Detectives assumed that because a contestant was good-looking he shouldn't be able to sing well ?
I admit that with the tone-deaf contestants always being 2 in number, it was easy to predict that the guest would end up with a good singer once 2 tone-deaf ones were weeded out.
I like that they've added this feature that the detectives can vote on which contestants they want to pick in each round. At the same time I wish they wouldn't get a guest or host to lip-sync in round 2. That part I tend to skip.

Anyways, this is one of my favorite variety shows, and I look forward to season 8.
