I don’t get the critique about some idols lacking stage presence. I always enjoy watching Red Velvet performances (who I’ve seen criticised so often). Is stage presence subjective? Also, how is it that the idols who are “called out” on their lack of stage presence are always female (Red Velvet, Twice, (G)I-DLE, etc.)? I rarely see boy groups being criticised for a lack of stage presence.
