Back in the 1930s there was the anthology movie If I Had a Million, and in the.1950s there was the TV series The Millionaire, about people who are suddenly given a million dollars by an eccentric tycoon and how the money affects them in their particular situations. Six Zeroes uses a similar device, but the characters are lottery winners and in order to save them from regrettable impulses, they're required by some regulation to attend counseling sessions before they receive the money. Is there such a regulation anywhere? If there isn't, there should be. Anyway, besides being about the people who attend the counseling, the series is also about the counselor, who has problems of her own. (Maybe that idea came from the TV series In Therapy?)
The lottery winnings are a McGuffin that serves to reveal the characters and their personal problems in some depth, and actors put the characters across quite forcefully, on the basis of a script that doesn't shrink from some uncomfortable scenes. I can imagine that likely this will be another Israeli series picked up for adaptation in other markets.
