I like the cheestastic nature of the show, and I'm going through it to see how many old timey science fiction stories I can identify. I am fond of the Twilight Zone and the old Outer Limits, and it was a bit of a thrill to find an even older SF TV anthology I'd never heard of, one dating back to the era of Red Skelton and Dragnet and Your Show of Shows.
It's an acquired taste, of course - one has to take it as bare bones theatre, "The Maguffinville Players Present SF", given the crude nature of special effects available at the time (most impressive stuff happens off-screen), but I'm finding it amusing. The music manages to create considerable atmosphere, and there's something interesting to see 40's and 50's science fiction stories taking place in an actual early 50's setting.
I'll have to agree with Plaat, though: there's a distinct air of anti-science in some of these stories. I can forgive it, given the era, with what appear to be "original" stories for the show, but I am less charitable to the cases where they re-write an SF story to give it a more anti-science slant. In the ones I've seen so far, the worst cases are the one where the scientist has a "I must not meddle in God's Domain! I shall destroy my probably world-saving technology!" moment - with Crucifix, mind you - which does not occur at all in the original, and the one in which a story which was originally a condemnation of government secrecy, censorship, and segregation of decision-makers from scientists turns into "scientists will gladly risk killing us all."
