Recently, I've been more careful about the kind of media I watch (still reading 'Not even a hint' and still not finishing up the writing of the article. hehe). I think one guideline that has helped me (besides knowing that God watches what I watch) is that whatever I watch should be material that I will not be afraid of letting everyone watch along with me. And I should not have to need to explain for the material in it (sadly, this criteria would have meant that I would not have watched Ouran high school host club. hahaa)
I think it's useful :) You can use it too if you want :)
