Sad To See This Great TV Series End
12 March 2007 | by (United States) – See all my reviews

This was the last episode of this famous television series. It wasn't planned to be the last, but the star, George Reeves, supposedly and sadly killed himself. (There also is a theory that he was murdered.) So, the writers, not knowing this was the last show, didn't do anything special with but it certainly was an interesting episode.

The Secretary of the Treasury and the President of the world Bank, along with old favorite Professor "Professor Pepperwinkle" are all in the office of Daily Planet Editor-in-Chief Perry White.

Pepperwinkle is there showing the reporters on the staff (all these years and apparently Clark Kent, Lois Lane and Jimmy Olsen are the only ones!) that he has invented how to make gold: the only person in history to achieve that. The government big shots have their doubts the stuff is real but Clark and Perry vouch for him and his honesty. The Secretary is understandably upset: if gold could made by the ton, it ruin the country's economy and the international banking structure. Perry knows this and it's why he brought all the parties together. They all ask the professor to promise not to ever make any more gold.

"And remember," says White, "I don't want any of this to leak out. That goes double for you, Mr. James J. Blabbermouth Olsen!!"

"Aw, chief," replies Olsen, "cross by heart, I won't spill a word."

Well, you can imagine what Mr. Blabbermouth inadvertently does at the local café. In no time, the crooks are at Prof. Pepperwinkle's lab demanding gold. "We ain't greedy, professor, all we want is a couple of tons of the stuff." They threatened to harm Lois and Jimmy if he tells on them.

Later, those two reporters are back visiting the eccentric scientist, who then reveals he has discovered what makes Superman strong: "positive kryptonite," as opposed to "negative kryptonite," which makes him weak. Both elements make up kryptonite as a whole and he has a good supply of the metal, he says, in his back yard. He also has a machine which could eliminate the negative part of the material so Superman would never have to worry about running into the harmful material again. By dividing the good and bad, he also can make a pill which just has the "positive" in it. Thus, anyone who takes one of these pills can instantly become like Superman! He demonstrates on a little mouse who is transformed into "Supermouse."

Jimmy and Lois think this is great. If they take the pills, they can catch all the crooks and scoop Clark on any store. They each take one no time, they are flying like Superman, bending steel in their bare hands, etc.!!!

Well, as I said, it was wild (and yes, silly) ending - planned or not planned - to a wonderful and extremely entertaining television series that still entertains us today. I wish they could have gone on for a few more years.
