This show was truly awesome. I loved all the actors, they did a wonderful job. I always skip all the shows intro music. But not for "Unforgotten". I fell in love with the song "Oh Wonder - All We Do" and the BBC series. The end of Season 4 was so sad, befitting of this song! I hope there is a Season 5 soon.

Loved it! The actors are excellent and the writing and storylines are interesting, intriguing! The first 3 seasons are great. Season 4 is not good at all.

Love this show. Well written. Tightly paced. I miss it, as it's unavailable on PBS or BBCA in US.
