Is it insensitive to make TV dramas and movies out of real life heartache?

Is it insensitive to make TV dramas and movies - out of real life heartache? ITV's multi-part drama 'manhunt' follows the investigation into Levi Bellfield, a serial killer who murdered three young women in and around west London during the early Noughties. The programme has been criticised with one review labelling it as "an exploitative theme-park ride through one of the biggest tabloid stories of the millennium." Is it really ok to dramatise horrific events, for entertainment? Murder. Suffering. Real lives and real people? Vinny got the views of commentators Bumper Graham and Liz Kennedy.
