I liked COS. It is a departure for the band,yes, but most KISS fans are deeply resistant to anything other than what sounds like Alive or Destroyer.

It is a very dark (for them) sound; not airwave friendly, but respectable in it's own way. I let people who don't listen to KISS hear this,and they were blown away by it.

Traditional KISS fans hate it,but some of us like Bruce and Eric Singer's work..including this.
