It shouldn't look like work, is what the reviewer meant or should have meant. A great performing artist will make the extremely difficult look extremely easy and they will always look like they are having fun or they will look, physically, like the embodiment of whatever song they're singing. If the song emotes joy, the performer should look joyous, if the song emotes fear, the performer should look fearful or hesitent, if the song emotes sadness, the performer should look meloncholy, etc... And as the reviewer began to point out, it is the subtlety of a performers gestures which defines their performance. A good performer will always hold your attention. And Michael is the blue print for what a performing artist should do and be.
