I mean, it's campy female detectives...with the right cast I think that can work anytime, regardless of if people even know what the tv series is. Had this starred Zendaya, Lili Reinhardt, Lupita, Emma Stone, JLaw, Emma Watson, Florence Pugh, Awkafina, it'd probably have been fine. You could even keep KStew and just go bigger with the other two.
But this was never going to sell with just KStew and two nobodies. And I do think Naomi Scott WILL be big eventually, but this was too soon to expect her to have any audience draw.
