Emmett and Ellie (David Tennant, Anna Gunn) work together, trying to retrace the steps of young David the night he died. Starting with tonight’s episode, this miniseries, patterned after the British miniseries Broadchurch, veers off onto its own path. From now on, according to the show’s producers, the story – even the solution to the murder – will be different. So if you’ve been avoiding this Fox series because you’ve seen Broadchurch already, maybe it’s time to give it another look. Compare and contrast.
