Other programs such as ones based in East London portray London as being not a nice place to live, with the use of high-rise flats that are unattractive and also everywhere looked a bit shabby. These sorts of programs make teenagers look scary and dangerous, especially teenagers that aren't white. This has an effect of making some people scared of these types of people for no reason.
On the other hand, there is an opposite of this. Films such as Notting Hill make London out to be very green and peaceful place. They mainly use white, well-off people and do not show many other ethnicity's or cultures.
Both representations are untrue as not all teenagers are scary and carry knives but little of London is green and peaceful and it is very multi-ethnic and multi-cultural.
