I'm watching some Super Sentai (and other tokusatsus) since more or less a decade because I want to watch full seasons in subtitled versions of some shows I used to watch when I was a child.
From the Super Sentai franchise, I watched Flashman (1986-1987), Maskman (1987-1988), Goggle V (1982-1983) and Changeman (1985-1986), from the 1980s, which I saw in TV in the 90s.
Some time afterwards, I was curious to see how Super Sentai looked like in the 2000s.
I chose to watch Gokaiger (2011-2012) cause it puts all the previous Sentai in the same show. It was the perfect plan to catch up with lots of Super Sentais at once. It was interesting.
Then, I watched Sun Vulcan (1981-1982) and liked it.
The series often have interesting soundtracks. The emotional thing works quite well.
The clichés are annoying. The standard episode scheme is: a plan of the vilains to conquer Earth + the Super Sentai discovers it + field battle + destruction of the monster of the episode, which gets big and is afterwards destroyed by the Super Sentai giant robot.
The drama inside is often interesting, notably if you watch lots of episodes in once, but they can be diluted by the clichés. And there are lots of episodes working like fillers, which contribute nothing to the general story.
The dramas of Flashman, Changeman and Gokaiger are quite elaborated. Flashman's one is particularly touching. Goggle V and Maskman are less interesting, and Sun Vulcan is cool mainly cause of the funny characters the Yellow in the Sentai and an employee of their chief.
Super Sentai have lots of fans in Brazil until today. I remember a Portuguese friend telling me how she was surprised to find adults guys singing tokusatsu songs in bars there :P
Besides Super Sentai, I also watched Gyaban (1982), Sharivan (1983), Shaider (1984), Spielvan (1986), Metalder (1987), Jiraiya (1988), Jiban (1989). The first three are a trilogy (space detectives) and movies interesting movies were released in 2012 and 2014. Spielban is a space detective-like series. Metalder is an android, the story is more mature, and there isn't the cliché of one episode = one monster: that's cool. Jiraiya is a ninja and Jiban a Robocop inspired hero. Hiroshi Watari, the actor who played Sharivan, Spielban, Boomerang in Juspion and the stunt of the Red Sun Vulcan was in Paris last month, but I missed him :(
I'm waiting a fansub to finish Juspion (1985, kind of space detective) before continuing watching to it and I'm looking for subtitles for Winspector (1990) and Solbrain (1991), rescue teams, and Machineman (1984).
All these are branded metal heros, cause they use metal armors. There's usually few main protagonists, often only one, whereas in Super Sentai they're often five.
And finally there is the Kamen Rider franchise. I watched Kamen Rider Black (1987) and Kamen Rider Black RX (1988). The first one is quite dramatic, and better than its sequel.
I watched all this to remember things I saw in TV when I was a kid. Now, adult, I find these series too childish. They don't attract me. Perhaps if they evolved like Saint Seiya (1986-1989), with a movie like Saint Seiya: Heaven Chapter: Overture (2004), focused on grew up fans, and well done animation like Saint Seiya: The Lost Canvas – The Myth of Hades (2009-2011), instead of childish and poor made ones like Saint Seiya Omega (2012-2014).
