Once Upon A Time In London - 2019 - 6/10

Scattershot overview of rival “Kings Of The Underworld.”
From the pre-WWII 1930’s to the advent of the Krays in the late 1950’s.
Ostensibly about two top bosses, Billy Hill and Jack Comer, we are early on introduced to a cavalcade of assorted henchmen, underlings, enforcers, specialists. Who are these guys? Confusion only grows as all seem to jump sides.
There are some capers and heists, but most action is retribution and knife fights.
Sex and gore is implied most of the time.
This will be better for viewers who know names and history.
For outside onlookers, this is a shallow sweep of greatest moments.
