It's not that it's wrong or sinful. It's rather simply that God takes no pleasure in it. There's no excellence there. I read this recently in book about television as a new technology. That is a suggestive way of looking at our work and at our lives.
Technology is a metaphor waiting to unfold.
A wristwatch, for example, is not simply a portable hourglass. A wristwatch actually changes the way we think of time. An electric light bulb is not simply a kind of more powerful candle. The light bulb actually changes the way we think of day and night. So also with television.
