When I saw the ending to this Twilight Zone, I was shocked that there was no real lesson offered, leaving the viewer with some twisted Nazi vision; a "final solution" to dysfunctional teens. The very suggestion of extermination as the answer to a problem was not effectively dealt with.
A few right wing nutcase viewers would enjoy the solution this show offered. A much better script would have been to show the bad things that happen by exterminating people for non-conformity to a community's social values such as the movie Pleasantville conveyed so effectively.
I did not feel this show was written well.
