The TV drama Unforgotten has this plot. A young black boy was murdered in the 70s and his body found 50 years later in the basement of a derelict building. The story flashes back and forth and a cold case team try and solve tbe case. It stars the excellent Nicola Walker and Sanjeev Bhaskar
Alien Resurrection. I first saw this at the pictures and thought it was ok, maybe because I dragged the missus to it I was feeling a bit guilty cause I wouldn't go and see her rom com films. It is still only ok.
I watched the first two episodes of Trial by Media. I was really looking forward to the series but to be honest it was somewhat lacklustre and half way through the second episode I was willing for it to end.
