Actually, the dinosaurs may very well have been the primary selling point! I believe one of the reasons that has been suggested regarding Toei and the use of dinosaurs for Zyu (which might have been suggested by August Ragone, I can't currently remember) was Toei's anticipation of Jurassic Park, which was released in America during the Summer of '93 prior to PR debuting during the Fall Season of '93, and according to IMDB, the release date for Jurassic Park in Japan was on 7/24/93, which is apparently the same date as the release of Zyuranger 22 which debuted Gouryujin! Toei might have done it because of the potential success of the movie, but Saban might have done it to cash-in on the massive appeal AFTER the movie became a success! Granted, the show was likely in production before and during the movie release, but Saban may have had the same idea or even learned it from Toei! It's possible, though I will not say definitively, that Jurassic Park is the reason why Zyu is dinosaurs, and by default, why Mighty Morphin' is dinosaurs! Thanks Spielberg and Crichton!

P.S.: Anyone ever realize that despite Mighty Morphin' being dinosaur-based, Saban and Co. never really dealt with the matter too much in Season 1! It's simply the given motif, but no genuine explanation was given at that time as to "Why dinosaurs?"

Aka "people on the internet".
If the toys are selling, kids must like it well enough. If that's the case then saying its not getting a "great reception" isn't exactly true.

It not appealing to the wider demographic of fans is a different matter entirely.

I think Haim does get involved only when it costs a lot of money like megaforce.

There's was a time Saban in cares with storytelling.

Yes, he's a giant, floating, all knowing digital head with a heavily down-pitched voice.

In an office in Burbank, California.

You realize old school Power Rangers is just as cringy as it is currently right?

You'll never see them do something like Bootleg Power Rangers because we aren't the target audience nor will we ever be.

At the end of the day, Saban is a CEO of a big company and to him, all he cares about is making money. He dosen't care about you, he doesn't care about the fans, nor does he care about story, so deal with it.

For now.

You're not serious, are you? Power Rangers is created to be marketed to kids. It just is. It always has been, and always will be. The decisions for each season's story rests with the staff for that season - for instance, SPD - Jungle Fury are all wildly different in some ways, but very similar in others, and they share the same tone. Seasons like Lost Galaxy, Time Force and RPM will always be exceptions that occur because of the current staff - never a thick-and-fast rule.

I wouldn't say never, depends on who owns the license. It's most probably true, but it's only improbable for it to have a massive target demographic shift, not impossible.

I personally doubt it ever will, but, who knows, maybe they might start making a sub-line of shows aimed at older fans, like how the toys work, with stuff like Legacy and Figuarts.

The fact of the matter is, Power Rangers is wildly successful right now, as it is. No one's going to mess with that status quo until it becomes unmarketable.

And when it comes to a massive demographic shift...if you're going to insist on looking at the slim chance of it happens, then you also need to analyse why. Why anyone who would want to buy the licence from Saban would want to go with that huge risk. And it is a huge risk. The 'adult demographic' you're talking about doesn't exist as a comprehensive whole. You have those who like things as they are, those who simply want series like RPM, or Lost Galaxy, and then there are those who want things like...that bootleg.
But even ignoring that, there is a much larger reason that anything massively different than what we have now is next-to-impossible. And that is, that Power Rangers relies on toy sales to function, and adult fans buy far less toys then kids do, because everything has to be perfect if it will live on a shelf, whereas a kid is just happy to have their favorite character to play with.
Less toys bought, and those toys needing to be a higher quality means a far narrower profit margin, if any at all. Which makes continued production of an 'adult' Power Rangers series impossible to sustain.
Which is why that second idea is impossible. Producing two series simultaneously would be a massive drain - even if, as you say, the second were to be much smaller. Why bother with that drain if only one series would be a profit anyway?
