One of my favorite writers, Jay Caspain Kang, wrote what was, to me, a fairly unconvincing piece about the show's "White reporter privilege." Justine Elias chided the show for being "slack and meandering."
But what I really appreciated was Sarah Larson's piece for The New Yorker on this topic:
Episode twelve conclusively proved that what we’ve been listening to is not a murder mystery: it’s a deep exploration of the concept of reasonable doubt, and therefore an exposé, if unwittingly so, of the terrible flaws in our justice system. Those among us who deign to be jurors, and don’t try to wriggle out of jury duty, too often don’t understand reasonable doubt, or can’t convince fellow-jurors about what it truly means. We convict people who haven’t been proved guilty because we feel that they are guilty. We feel that they’re guilty in part because they’re sitting in a courtroom having been accused of a terrible crime. In cases like this, the burden often ends up on proving the accused’s innocence—not innocent until proven guilty. And Adnan Syed is just the tip of the iceberg.
Even if the show doesn't accomplish anything in the legal case of Adnan Syed, and even despite its other potential flaws, "Serial" has highlighted some of the systemic flaws in our justice system to an audience of millions of people. For that reason alone, it deserves our praise.
