Critic reviews

"The landmark series was Dimension X, which was broadcast by NBC....It was the first radio series to treat science fiction in an adult way." (Mike Ashley, Transformations: The History of the Science-Fiction Magazine 1950 to 1970)

An ark in space that loses it's purpose.

Would you consider the audio edition of Dimension X to be better than the print version?

Never read the short story but I enjoyed this Heinlein story about a space ship that had been in space so long that after mutinees and factions creating their own religion lose all sight of the original purpose of the mission.

What did you like best about this story?

The mutants were more humane than the humans. Sad but so true.

Which character – as performed by the narrator – was your favorite?

The head mutant who shows the young scientist the errors of his beliefs by opening the spaceships shields to display the universe outside. That was an awesome moment.

Did you have an extreme reaction to this book? Did it make you laugh or cry?

It made me angry that the powers to be refused to listen to any reason and only after they had no chance of survival did they realize that the young scientist and the mutants were telling the truth.

Any additional comments?

Great Heinlein story, dramatically told.

Needs better audio

Great story, Great Actors, but the experience is ruined by very poor audio... the sound effects overwhelm the dialog to the point of making it unbearable to listen to. PLEASE PLEASE check the Levels and re-release.
