Frankly, being an old-skooler, I'm with The Next on this. It doesn't hurt to have a thread about the ups and downs of Super Sentai in general.
Although there are things about the newer Super Sentai that I like (the Boukengers have the best costumes of the newer teams, IMHO, and Doggy Kruger is my absolute favorite character in Dekaranger), they just don't pack the same punch as older shows do.
I agree that the 70s and 80s are indeed the Golden Age of Super Sentai. Dynaman is still my favorite series (it's the first one I saw, thanks to Night Flight), but Dynaman was what got me into the series. I enjoyed Goranger and Battle Fever J a lot. Seeing early episodes of Goranger brought American comic-book superheroes to mind (as did BFJ). IMHO, Dairanger was the last best series for me.
Another reason I prefer the older shows, was that the heroes, even though they were pretty-idols in their day, were definitely more mature! Men looked like tough, strong men, and women were basically amazons! Compared to all the cutesy teenagers of today. They were wimps outside their costumed counterparts, and are so mechanical. And what the hell is with those pajama-like uniforms!?
But there I go rambling again . . . back to the subject at hand:
There are three kinds of people:
-True Super Sentai fans who'll probably watch it, because it's, well, Super Sentai.
-Power Rangers fans, who got into Super Sentai by way of PR.
-People who have similar tastes to American annie-mae fans, ie. fascination for bishi heroes. This applies also to many of the current viewers in Japan.
Generally, Super Sentai is SUPPOSED to be aimed at the kiddie crowd, but kids deserve better than this. It seems that every superhero (with the exception of Ultraman the Next and Ultra Seven X) is all bishi. There's no variety. And one of these days, it'll lose its relevance. (I hear that bishi is somewhat in decline in Japan, and people are going for tough action stars like Vin Diesel.)
And LET'S NOT FORGET, some fans who love new tokusatsu generally blast old stuff for being "fake," "cheesy," "outdated," etc., and lean towards the more "stylized" and "realistic." stuff (and in some cases, dark and tormented). That really hurts. (This applied to the newer Godzilla films, also.)
So yes, you'll be seeing quite a bit of talk about newer Super Sentai, because it's new and treated as a big deal (so of course older stuff will be pushed into the background; in some cases, they don't mean to be disrespectful about that, but in others, that's pretty different). It's all about relevance.
I don't participate in any discussion of the newer stuff, as I've already made it very plain that I lost my faith in newer Super Sentai years ago, partly because of its increasingly close relationship with Power Rangers. I see no more point in it. (I don't care for localizations very much.)
