This was a Ray Bradbury story brought to the small screen.
I'm surprised that fellow reviewers didn't like this episode as much as I. What's not to like. It was really scary at the end.
I guess one could argue that there's a little too much left to the imagination. But then again, that's one of the things that makes this show great.
We don't know what it whispered in the Aunt's ear at the end of the show by who appears to be spawned genetic evil, but we can guess. That's what makes it scary, too.
The old man delivered a deranged performance, too. Well done.
