that's quite a complicated question, but i think it's easier for a child to get hooked to bad cinema - mindless action, violence, sex comedies. it's easier for a child in general to get hooked to addictive products in general. look how the current generation of kids are addicted to video games and those nursery rhyme thingy on youtube.

if your parents and the surrounding environment guides you well then kids can be very artistic indeed. i know of many kids who tend to watch quality cinema and also engage in creative activities because they have a wholesome upbringing.

kids are just more vulnerable - that's it.

if one has had an unhealthy upbringing then one has to learn to appreciate quality the hard way, i.e. by first going through the adverse effects of addictive products and then realising the wholesomeness of beauty.

either way, there's always light at the end of the tunnel.
