I think in a good film - every scene prob should have LCD - laughter cry or drama but it should also have a P - a unique personal detail.
It could be anything - a man using an Asthama machine or eating a tic tac toe, or a child walking in father's shoe, or henna colour in hair but you need to add these personal details... and you need to revisit every prop - colour of ink on the paper - or brand of the pen- don't make it generic - make it specific ...
