If a Church is mostly empty on Sunday, do you consider that Church Spiritually Dead, or just Ineffective?

Many Churches are empty today because they do not embrace diversity, and they are out of touch with the Younger Generation. Young People do not want to go to an Old Time Boring Church, instead they want a vibrant Church that bridges the Generation Gap, with a Youthful Choir and Ministry. The younger generation is more open to diversity than past generations. I think any Church who is not open to diversity and the youth movement will find itself empty at some point in the 21st Century. I have seen this first hand in numerous churches across the land.
