The reason Britney was ever a star to begin with was because bitch could entertain.
From BOMT, to great performances, to her fascinating personal life, to her trainwreck downfall, the people are only ever as invested as she is entertaining
Between her boring middle-aged soccer mom with no knee personal life, and her non-existent to robotic promo performances, she is just not entertaining, which is why it does not surprise me she is underperforming
but the interviews are giving me hope that some spark is left/back in her

we'll just have to wait and see
