AVClub:Veep has one of the best ensembles on television. The show is incredibly dense, its rapid-fire dialogue ensuring that in most episodes, every regular is given at least one memorable line. Even when characters are silent, there’s plenty of nonverbal communication and comedy happening in the corners of the frame, each cast member reacting to the mayhem around them. Often in these reviews, it’s hard to decide which performances to focus on, as everyone is on their A game and there simply isn’t enough space to mention them all. Not so with “Mother,” which pulls the ensemble back and hands much of the episode to the fantastic Julia Louis-Dreyfus as Selina deals with her mother’s stroke and eventual death.
