What makes a good Romance/War film?

There are many popular stereotypes that come with the Romance/War genre. These not only give the audience and expectation of what they are about to see but also helps them bond with the film and the characters as they may have experienced similar things within their own lives.

Audience.

I think the main audience for this sort of film is for the older generation as they are more likely to appreciate the effects war had upon people during the time it was happening and also they may be able to empathise with that character. I also think this is one of the main reasons why most war/ Romance movies are filmed in black and white as this relates to the older generation more.
