Without giving out spoilers...
It is stylish and cool to look at.
However, if you engage your brain at all you might find there is little sense to it.
Firstly, the flashes backwards and forwards stinks of a director desperate to keep your attention rather than deliver an interesting story.
As the series goes on, you might realise that the female leader of the gang has never done anything to gain her fearsome reputation nor to create a syndicate of mafioso from around the world, including hunting down the one person who can break this centuries-old mega safe. In fact, the only impressive thing she's done in her past is read a car company's AGM report. That's the main plot undermined then.
Smaller weird detail you might notice: In a later episode, a 50yr old gangster called Gareth is playing PlayStation with his dead mate's teenage daughter. Judging by how quickly him and his 7 gangater mates turn up armed, they must have been having a PlayStation party at his house.
Last episode tries to make some sort of societal moral but it lands flat. Finally, the "antagonist" probably needs to speak to his accountant if this heist is leaving him suicidally broke.
