And while the Olsen twins' parents were able to milk their kids for profits for years, they have ruined their daughter's careers.
The two of them are simply horrible, talentless actresses. 10 year old girls with little discernment can enjoy a movie starring two 10 year old girls who can't act, but 20-something moviegoers (1) will have no tolerance for truly terrible acting when there are plenty of hot young starlets who actually have some chops and (2) will have no tolerance with a series of hokey plots that center on "identical twin sisters who have very different personalities".
They grew up in a hothouse acting in projects tailormade for them, and as a result they never had to do what other young actresses have had to do - work for a director (instead of having a director Daddy hired work for them), fight for parts by relentlessly honing their skills, play maladjusted or evil characters, etc.
They have no emotional depth, no range, their shtick is old and they have nowhere to go.
And despite the constant stories about how big their media empire is, I guarantee that Dakota Fanning already has more money in the bank than they do and she is just beginning a long and brilliant career.
I am not sure they care if they ever act again. They are really into the business side of their merchandising empire.
But the twins are moving away from film after their disastrous New York movie, aren't they? Because you're right; they can't act. Now it's just about keeping that money machine working overtime by going down different revenue driving avenues.
