I'm too old to have cared when the original Power Rangers phenomenon happened in America. I've taken an interest in some of the Megazord toys, but that's pretty much it. Thus, I was hoping to hear this movie was really good because I would have found it interesting to finally actually care about this property.

That being said, for those who don't know, the original Japanese version of Power Rangers (Super Sentai) spun out of a Japanese Spider-Man TV show.

When, the Original Power Rangers were first on Television back in 1993 my three nephews were enjoying the show and despite their parents misgivings they were allowed to watch it after school and do their homework afterwards. I asked my three nephews about it and they weren't interested in seeing this movie because they outgrew it back in the late 90's; and that's why they aren't interested at all.

So, No Power Rangers for me and my nephews that enjoyed the originals.

Usually it's a team of five or six young people that can transform into costume wearing martial artists that take on forces of evil. What makes Super Sentai stand out is that every year is a new, different story with a different cast with completely different circumstances. Yet a lot of stylized aspects of the heroes remain the same. They're always wear color coordinated costumes, know martial arts, fight monsters, have long monologues, use robots that transform into a bigger robot, and invoke theatricality with dramatic poses. Very over the top, the shows usually play it straight. I've enjoyed the original iteration of Japanese iteration of 1993's Mighty Morphin Power Rangers (named Kyōryū Sentai Zyuranger in Japan during 1992) which I think was the 17th Super Sentai produced. I could see why it was changed for the initial US release in 1993 though. Some things would have been just too hokey for American audiences to wrap their heads around at the time. Interesting to see what the producers of that show had to come up with on a limited budget and time frame in order to make an action show aimed at children. Honestly I still think the costumes, weapons, and robots from that one iteration of the show look cool to this day. 

The Sentai/Super Sentai  series (essentially) grew out of a few things:  Ultraman, Kamen Rider, and Science Ninja Team Gatchaman (aka Battle of the Planets, aka G-Force.  Ultraman debuted in the 60s, with an alien hero fighting monsters, aided by a scientific/military force with individual vehicles.  That series spawned imitators and new versions of the show (the various "Ultra brothers.").  Kamen Rider debuted in 1971, featuring a masked hero who fought an alien criminal organization and its soldiers.  The hero was created as an experiment by the villains and rebelled.  A unifying feature of Kamen Rider and Ultraman (aside from new series debuting every few years) was that a human hero transformed into the superhero.  Each new version got a new costume and weaponry/vehicles (and support team, in the case of Ultraman).  Next, the animated series, Kagaku Ninjatai Gatchaman (Science Ninja Team Gatchaman) gave us a squad of heroes, with themed costumes, individual weaponry and vehicles.  The young heroes had a special watch-like device that allowed them to transform into their superhero form.  They had a team mothership, as well as their own vehicles.  Each had a particular role:  serious team leader, hothead tough fighter and number 2, female tech expert, slightly dim member (and/or pilot) and impulsive younger member.  They fought an alien organization bent on conquering the globe, a group with a chief commander, various colorful lieutenants, and an alien force guiding things.  This then led to a live action series that combined these elements:  Himitsu Sentai Go-Ranger (Secret Task Force 5 Ranger).  They were secret agents (like Gatchaman) fighting an evil (alien) organization.  At first, they just had weapons and standard, but stylish vehicles.  That grew into the battle mech robots, with the Japanese Spider-Man tv series (also done by Toei, the parent company of Kamen Rider and the Super Sentai shows) influencing the concept.  The first "true" Super Sentai show (rather than just Sentai) is considered to be Battle Fever J, which followed the Japanese Spider-Man.

Battle Fever J was also tied, sort of, to Marvel Comics.  The team is international and the American member is Miss America.  All of the heroes are like their country's Captain America.

One of the later series, Chojin Sentai Jetman, was a direct homage to Gatchman, as bird themes made up the costumes and the weaponry and personalities mirrored the Gatchaman team.  This was the series preceding Kyoryu Sentai Zyuranger , which provided the footage for the first US Power Rangers show.

Ultraman and Ultra Seven were syndicated in the US, as were some of the later Ultra shows.  Kamen Rider V3 was shown in Hawaii and a few other US markets and then Saban's Masked Rider mixed footage of the tv series Kamen Rider Black, Kamen Rider Black RX (main source) and the movie Kamen Rider ZO.  The original Japanese Kamen Rider series also drew inspiration from a previous manga and tv series, Gekko Kamen (Moonlight Mask), with a different motorcycle riding hero.

If I see the new film, I'll wait til it's on cable.   Nothing I've seen or heard has motivate me to buy a movie ticket.  I use to watch Mighty Morphin on tv and while it it hokey it is still fun to watch.  I thought the series got better when it added Lord Zedd as the main villain.  I watched Power Rangers up to PR IN SPACE dropped out for awhile and I did watch Dino Thunder when I head Jason Frank as back as Tommy then dropped out a again,  did watch a few episodes of the Super Ninja & Mega Force series but was not really into it.

BTW If anyone is interested or didn't know this at least most if not all of the Power Rangers shows can be found on NetFlix stream.
