In listening to this show I was reminded of The Outer Limits, Twilight Zone, Dimension X, etc. I especially like RMT episodes that go into genres other than horror and mystery. It was hard not to anticipate the ending of this show, because the whole theme of testing the human race and finding them just far enough above total scum to be worthy of existing has been done in so many sci-fi stories. But I liked the show because it was sci-fi and because the characters were believable. Radio transmissions and strange voices from space are effective in radio drama.
