Queen of the South, which premiered last week on USA, looked like a reasonably promising new crime show about the rise of a young drug runner, Teresa Mendoza, played by Alice Braga. The pilot had a lot of action and made Teresa a compelling figure, but I wondered where the show would go after introducing its premise and characters. Well, I’ve now seen Thursday night’s second episode as well as a third hour, and I can tell you it’s a good show with a supporting player who, to my thinking, becomes even more interesting than Teresa in this early part of the series.
