Goodness, this needs to be repeated so often. The only way you could "butcher" Super Sentai is to add alterations to them like George Lucas does to his Star Wars movies and declare all previous versions non-canon. Even in that extreme end, there's nothing saying that you can't have your own personal preference for the originals. Just ask those non-Special Edition Original Trilogy purists for Star Wars who just turn a blind eye to the alterations. (For that matter, I'm fine with the Star Wars alterations.)

As it stands, Super Sentai and Power Rangers are two different things. One does not supersede the other. Power Rangers Megaforce is not Tensou Sentai Goseiger 2.0 or Kaizoku Sentai Gokaiger 2.0. It is simply Power Rangers Megaforce.

I've been under the assumption that sentai also has a more adult focused fanbase than the rest of the world and I would even say the amount of higher end product put out would/could support this

Unlikely. Things like Figuarts were always a collector orientated line.

That's my point exactly. That lines like that are strongly supported in Japan just enforces that sentai has elements marketed more to adults than power rangers in America.

I think Super Sentai has always been seen as a kids' show in Japan, and any adult fanbase is similar to our Power Rangers fanbase in scope and proportion. It may seem more mature than Power Rangers, but I think this is simply because more relaxed standards for kids' television give writers greater freedom to write smarter kids' shows. In this respect, it is similar to Western shows such as Avatar the Last Airbender, Star Wars: The Clone Wars, many Marvel/DC superhero shows (Batman TAS, Justice League, Spectacular Spider-man, Young Justice) or even My Little Pony: Friendship is Magic.

So you're right in that they might have a larger focus on adults, not because the fanbase is necessarily bigger, but simply because they are willing to tap into that small market. Saban, however, at least in the case of Samurai, seems to have made the decision to focus almost entirely on kids because profits are not hurt a lot by this focus (adults still buy Samurai merchandise). This may change with Megaforce as we've seen marketing more geared towards collectors than Samurai was. Hopefully this translate to the actual show too.

What is with this my little pony friendship is magic I keep seeing hints of on here?

Bronnies are everywhere. They are beyond help and all you can do is save yourself from the same furry fate. :p

I am not a furry. I just appreciate the show and the characters for what they are, and enjoy reading crossover fanfictions starring the characters, as well as adapting real people into possible characters for the franchise. I draw the line at human/pony romance.

Hello sir. Have you accepted Twilight Sparkle in your life?

It's a little girls' show about ponies that turned out to be far more amazing that it ever needed to be. Very mature (not darker or edgier, just clever) and epic stories, great jokes and humor, very complex and fully likable characters, a plethora of great songs that recall the Disney Renaissance, a fully realized and living world and mythology and well-written dialogue makes My Little Pony: Friendship is Magic the go-to show for many who seek a sweet, fun time.

The show's quality has spawned a dedicated community of fans who are outside the demographic of little girls. It was surprising to see grown men, in particular, become such big fans of a show about colorful ponies, but I think this article would explain it a bit more.
