I watched the first couple of seasons of "Unforgotten" as season four was highlighted on the Guardian's top TV of 2021 list. They disappeared before I could watch season three though, however, the impending arrival of season five saw them return to ITVX and I watched the third season. Despite its grim cold case theme, I still rather enjoyed it.
When a body is discovered during refurbishment work on the M1 motorway, Cassie (Nicola Walker) and her team are called in to investigate. They determine that the body belongs to Hayley Reid, a 16-year-old from a village in Hampshire who disappeared on New Years Day in the year 2000. The investigation comes to focus on four friends, Chris (James Fleet), Tim (Alex Jennings), James (Kevin McNally) and Pete (Neil Morrissey) who were holidaying with their families in the area at the time. Ironically, at the time the body is discovered, each has a separate reason for not wanting to become involved in the inquiry.
Again, I don't really like police procedurals that much, so it says something that I have watched three seasons of "Unforgotten" and plan to keep going. I rolled straight from the first season into the second and did feel that it suffered a little bit by being more of the same, so perhaps the gap I've had here ahead of the third season helped as this was the best season of the show so far. The case was really strong and presented all the principles as viable suspects and (without spoilers) I did like the resolution of this one being a different to just being someone who made a mistake and has been living with it for twenty years.
The personal storyline for Cassie was interesting, as she genuinely starts to wonder whether she should stick at this job, particularly when her accident in this one has catastrophic effects. I know that Nicola Walker is only doing one more series, so it does feel like we're feeding into a storyline with a resolution.
Bit of a gap and then onto season four I think.
