Protect our children - ban advertising of horror films in public places

Currently in Edinburgh (and I assume throughout the UK), bus stops are advertising a film called Annabelle Comes Home, which features a picture of a demonic looking doll. My four year old is terrified and refuses to walk past any bus stop which displays the poster. It's not the first time she's been traumatised by horror film advertisements at bus stops and on buses.  Anyone who is involved with the care of a young child (and with standard degree of empathy) will understand that it is utterly cruel to expose young and fragile psyches to advertisements which are intended to scare much older age groups (in this case 15+).

I know I'm definitely not the only parent who feels that advertising films with a poster that is designed to scare is unacceptable when it can be easily seen by young children: https://www.mirror.co.uk/news/uk-news/mums-fury-poltergeist-movie-bus-5744955 

I promised my little one I would do something.  Thank you very much for your time and attention.
