This story was clever and fun, but certainly more form than substance. For a SF podcast, the radio format is an obvious match, and it kept the tone close enough to reality, even if it was not pitch perfect. I had Jeff Bridges in the beginning of 'Fisher King' in my head (excuuuuuuuse me). Any way, the story didn't really go anywhere unexpected (aliens are so obvious), and it is a challenge to tell a story by means of pure exposition in an exciting way. The gradual reveal was OK, but didn't exactly have me on the edge of the seat. I think if there had been more than one phenomena or at least some kind of development in the outer world, it would have been more interesting.
