The nature of the Hollywood star has changed dramatically from the mysterious, alluring, larger-than-life goddess (Garbo, Dietrich, Taylor, Vivien Leigh, Jean Harlow...) to the glorified cheerleader type. There are only a handful actresses with the kind of pull the old ones possessed - these days we're mostly just bombarded with the most easily lead/manipulated stars - and that goes for any kind of popular culture, really.
IMO Sasha and Snejana are more related to the movie star of the pre 70s than todays stars. Todays stars are just required to alter their shapes, keep face and talk prettily in interviews....it really is extraordinarily boring. So in a way, thank god for Angelina, Lindsay and Britney - at least they seem to be alive, not mere celebots...
