I used to appreciate the Watchtower's concern regarding violence- thinking it was always well meaning but when you bring up the fact that they never satisfyingly answered any real social questions other than to open up the typical article, then it really wasn't. Because of those articles I naturally stayed away from most graphic violence and saw it as 'evil' or whatver.
But now as an adult, I recognize that violence is an element of movies and literature because it addresses real fears in humans, settles conflict or causes it. It can be used to be an almost metaphor onscreen or in a book for a certain fear in society or in us personally, to take an abstract look at violence or sex for that matter. The WT couldn't possibly be expected to 'go there' in any of their writings but now that you can separate their agenda from conventional explanations it's easier to see that violence is not evil simply because it appears in movies or books.
