This was a serious and thoughtful series much like "The Twilight Zone"(which aired at the same time) but one which isn't as well remembered or aired, which is a shame, but modern audiences may consider this show talky and slow, as it certainly is different than such anthology series today, which are all about shock value and quick editing.
This series wanted to make its audience think about the potential folly of human nature('The Architects Of Fear') or possible first contact with aliens gone awry('The Mice') and so on. Some episodes were whimsical ('Behold, Eck!) but would still create much imaginative speculative fiction about a two dimensional creature. Of course, you would still have episodes about a sand shark on mars('The Invisible Enemy') to provide the kids with typical monster thrills.
Interesting series that is on DVD, with a memorable disembodied voice introducing the premise and pretending to take control away from the viewer for an hour, which may be the only way you can see it, since unlike "The Twilight Zone", this doesn't get any marathons!
