My answer would be pretty much the same as for books. The medium is cheap enough that a person - or small group of people - with a vision can enunciate that vision pretty much directly to the reader or viewer without the distortion of too many intermediaries. So much mass entertainment these days is so processed, politically-correct, and focused on the bottom line that it isn't even engaging, never mind things like fun or inspiring. However, anime is one place where interesting content can still happen frequently enough to make it worth making a habit. Not that every anime is good of course. In fact, Theodore Sturgeon - an old-school science fiction writer - once paraphrased Arouet (aka Voltaire) by saying that 90% of everything is crap. (He also went on to say that any genre should be judged by the other 10%.) I tend to agree. But maybe for anime the good stuff is more like 15 or 20%.
