The dumbest moment in PR history? The entirety of Super Megaforce for sure.
That was the biggest waste of money, time, and source material in the millions of years in the history of mankind, period.
Sticking the series to a channel that loves to force hiatus, takes the second spot of "the dumbest thing in Power Rangers history".
Power Rangers is a series where it
must be one continuous season of 35-45 episodes. Splitting that into 2 seasons plus splitting it even more due to the hiatus, doesn't help in the slightest, because by the time the series is back up, some kids may have forgotten about it already. Not only it doesn't help toy sales, it also doesn't help the show.
For me, it's anytime they forget that SPACE IS A VACUUM. Like, I recall a moment from Power Rangers: Lost Galaxy where some UNTRANSFORMED CHARACTERS were jumping FROM ONE STARSHIP TO ANOTHER. IN THE VACUUM OF SPACE. BOTH SHIPS MOVING AT HIGH (albeit matching) SPEEDS.
The first (and I think most popular) example of this is in....well, In Space.
The Black Ranger takes a boy into space on a Galaxy Glider, which is fine.....until you realize the boy didn't wear any suit for space travel
