I think the only real genius of Serial was using a slick style and conversational tone as a gloss for what was quite poor (and arguably irresponsible) reporting. As an example, the whole Best Buy charade was only reenacted either out of their unfamiliarity with the facts of the case (the court transcripts reveal the exact location of the phone), or with more cynical intentions, depending on how generous you want to be.
