Which groups do you think are bad dancers? As a group not individually. Don't confuse stage presence with dancing.
1. Stray Kids : Their main dancers are Lee Know, Felix & Hyunjin. This is their level of main dancers. This is probably the worst male dance line I have seen. Lee Know is good but Felix n Hyunjin got those positions because others are even worse. When you compare Stray Kids dancing with other 4th gen groups dancing, it's laughable. Take kingdom for example. Stray Kids were embarrassed seeing BtoB a vocal group not known for their dancing put on better performance of their song. That d4 stage was bad. That choreo is bad but Blackpink can save it with their personality. These guys looked clueless. They have more stage presence when they stand than when they dance. Even their fans know this.
2. Aespa : Karina is their main dancer lol. Has sm ever had worse main dancer in their history? They really dance like robots. No expressions. No fluidity. No wonder they have the worst stage presence ever.
3. Blackpink : Now me hear me Lisa is a great dancer. Lilifilms show that. Rose is a great performer. While performing I'll take Rose over Lisa but Jennie..... That girl is lazy af. Never seen more entitled idol than her. She hogs that center more than half the song. Jisko works hard but she is not natural. It's visible. Blackpink have good dancers but as a group they are really bad. Their choreos are worse.
