In the acclaimed series “Succession,” which centers on an absurdly wealthy family constantly at each other’s throats over who will take control of their massive media empire, one of the most memorable scenes came when Brian Cox’s menacing, manipulative patriarch Logan Roy tells his children he loved them, but that they were “not serious people.” It’s the last thing he ever said to them.

In Cox’s directorial debut “Glenrothan,” which centers on a less wealthy family that’s still frequently at each other’s throats over who will take control of their whisky distillery, there are no such devastating, well-written scenes. Instead, the only thing that’s fundamentally unserious is the film itself.
