I have binged this series s01 to s03 in one week. (I know ,slow , right? ) But it's gripping, it shakes you to the core. The characters are crisp and yes most of them have a history. It tells us about greed , control and will to fight. A simple yet astonishing concept, the title Goliath explains it all, that how David, here Billy McBride, defeats big corporate giants, Goliath. Expecting the 4th season eagerly.
