4th gen choreographies are made for tiktok and look boring without fancy camerawork. (ex: Aespa)
They don't sing live. (ex: all groups)
They do the exact same facial expression for every single performance and have clearly practiced with cameras beforehand. (ex: rookies from big agencies)
They do lots of special studio performances where they mash together multiple takes, not showing their unedited performance skills. (ex: 4th gen groups who can afford it)
4th gen groups could be great performers. They could be terrible. Who knows.
