The first time I tried watching Unforgotten I thought it was a little boring but then I gave it another try and ended up binging all 5 seasons. Nicola Walker is an absolute treasure as DCI Cassie Stuart who is determined to find justice for cold case victims.
Each season pretty much plays out the same way, they find the remains of someone who has been dead for several years and they identify them. As the investigation proceeds we get glimpses of four or five people who could've possibly killed the victim. All five seasons have this exact same premise which sounds like it wouldn't work but it actually does.
I had absolutely no clue what was going to happen at the end of S4 and I cried my eyes out.
