Youth Drama films are more popular in the UK, Notable films include, kidulthood, and attack the block. these films tackle issues that teens in London face growing up, and concentrate less on celebrating the idea of youth, but focus more negatively of the pressures being a teen have growing up, these issues may include drug use, teen pregnancy and gang crime, which where the main themes in UK youth drama Kidulthood. They are seen as being more realistic than high school dramas, however they are quite exaggerated.

High school Dramas are predominantly based in the US. they are more positive than Youth drama and concentrate on celebrating the idea of youth and being teenagers, an example of a high school drama is High School Musical and Mean Girls. Although they acknowledge the joy of being young, they do also tackle the issues a young person may face in a high school, most high school dramas support the idea of social stereotypes, and the issues that come with it, such as cliques in high schools, and not being able to fit in, however in high school dramas this problem is always overcome with a positive solution to benefit the protagonist of the film.
