How huge is Power Rangers in Japan? Is it really that big a thing? I know they had dubs of the old Saban era series for a while. I find the prospect of them wondering when the subs are coming in for Power Rangers Super Megaforce or something really amusing.

I remember google translating some of their reactions to various PR stuff posted on Niconico. From what I got from google's horrible translations, their reactions range for awful-to interesting-to hilarious, like their reaction to Daggeron from Mystic Force: Hagrid?!

As far as I'm aware the dub every series, and usually the actors dubbing it are the actors of the original roles in that series.

That's actually not correct. In some instances they've gotten the actors back. But it's actually more rare than you'd think. More often the case is they just get new VA's to do the roles instead of the original cast. Though for SPD they did get the Dekarangers back. The Samurai dub I think may feature a few returning actors, but nowhere near the entire cast.

My bad. I honestly don't know a lot about this stuff, I just know that Power Rangers is pretty popular in Japan and so was Dragon Knight, perhaps more than here.

Power Rangers is available on Toei channel only.
There are less viewers than you think.

This is also true. It isn't streamed on a major chanel or website. Just the Toei channel. And not everyone has it.

There of course is a following for it in Japan. Enough to warrant the dubs. But it isn't even remotely as popular as sentai is over there.

They look awesome to me. =)

Red reps evil and blue reps the good so his red side being more jagged is understandable. I just wish they showed Red Kikaider and the blue Perfect Kikaider.

After getting a better look at the suit I'm still very happy they are playing up the whole Frankenstein monster on the red side much like Meimu did in the Code 02 manga. With the more info out I'm glad the kept the professor Komyoji as the creator and I love the new twist on DARK origination just being called ARK. I also think it cool bring back the original Jiro Ban Daisuke from the old show (which i'm still looking for a sub of if any one know a place) i just hope this goes farther than Gavin did
