Our Take On Sweetpea
It’s A Great Role For Purnell
One ofthe mistakes ofYellowjacketsseason 1was its decision to sideline Purnell when her character added a lot of potential and natural conflict to the Showtime series. But the move has allowed the rising star to take on arguably more multi-faceted performances inFallout, a major Emmy-nominated hit, which is returning for season 2.Sweetpea, though it’s a very different darkly comedic tale, looks to do the same by banking on the talents of its lead star.
