Tatiana Maslany Did a Fine Job.
Tatiana Maslany was "age regressed". Probably with an appliance or padding to suppress her hips and bosom. Annette Funicelo, of "The Mickey Mouse Club" was getting a trifle adult for the role and she, too, was age-regressed.
Maslany did a splendid job. "Ghost" was a classical sociopath without a moral compass of any sort.
All the more dangerous because her age and gender disarmed people.
Chilling performance.
