SEASON PREMIERE: This is the premiere of Season 3 of Broadchurch, the imported British series starring David Tennant and Olivia Colman as police officers – one local, one not – with very different approaches and personalities. It’s the final season for this series, which, like the others, actually is an eight-episode self-contained miniseries, in the mold of the original Prime Suspect. But though the central mystery story stands alone, expect to see several familiar faces, and characters from the previous two seasons – because they’ll be popping up.
