The opening of 'My Boy Jack' appeals to audiences by having a big, well-known star in the TV drama, which is Daniel Radcliffe from the Harry Potter movies so it appeals to mass audiences of both adolescents and adults. It must have had a high production budget for it to be a high quality film as the performance style is realistic.
However, because it's a war film it could be mainly targeted at males, from a stereotypical perspective, as the sequence shown only depicts men, not women.
On the other hand, 'My Boy Jack' may appeal to the older generation mostly because the TV drama is set during World War One, making it part of the historical genre, so they are able to relate to it more, which links to personal identity (finding that some aspects of a text reflects yourself) which is part of the audience's uses and gratifications, due to their social demographics. In addition, this links to audience pleasures - genre communities because every genre has their 'own' audience. For 'My Boy Jack' an older audience is more applicable due to the counter-reading of the film being part of the historical genre. The time when the story is set is evident through the mise-en-scene as old-fashioned costumes are worn. There are soldiers in the navy shown wearing a military-style uniform and the close-up shots of the cars indicate the time when the story is set too. A famous writer, Rudyard Kipling, is presented in the TV drama which is another reason why the TV drama relates to the older generation, as Kipling was a well-known and an important person during the time of the war.
