Haven't see the original series called The Syndicate (BBC) but the whole premise looks familiar.
Anyway, it's about a group, of people of the lower working class, who won 145 millions in Lottery. For everyone there is a twist though that prevent them from being happy with the money they just won. Personal problems, A LOT of bad decisions make them miserable.
This a TV-show that may (or may not) have the message that Money isn't everything in life. But to tell you the truth with 25 millions each they could turn their life in a careless direction and never look back. The whole drama seems unnecessary and with that kind of money they could easily change their life, and if not anything else, move as far as they can.
The production is OK. Performances are OK too. The pilot sets the mood and the subplots for the episodes to come. It tries to pass some messages about the human nature and our society, but seem kind of pretentious.
Overall: Give it a chance
