Indiewire:
Come for the incisive takedown of white collar culture, stay for Matthew Macfadyen's brilliant (and bizarre) comic turn.
But the real scene-stealer is Tom, played by the always great Matthew Macfadyen. As Shiv’s longterm partner and an employee at the Roy family company, Macfadyen gets not only a comedic turn, but a bizarrecomedic turn. Tom is a different person to everyone. At work, he’s a people pleaser to his bosses, who are also his would-be father- and brothers-in-law. Macfadyen maintains a “I can take anything with a smile” look forsuchdismissive assaults it’s impressive he can make it convincing — but he does. With those underneath him, mainly a new-hire (and family cousin) named Greg (Nicholas Braun), he’s as cruel and rude as his bosses are to him (the “Chain of Screaming” from “How I Met Your Mother” comes to mind). With his girlfriend, he’s silly and romantic; he’s charming, even.
So, which one is the true Tom? Is he a company climber, only in his relationship for its connections? Or is he a St. Paul simpleton, in love with a woman but corrupted by her family?
