It has been years since they subbed more Changeman, not to mention Zyuranger.
Dairanger is the only show that they are trying to finish at this point.
While I cannot speak on Changeman's behalve, the reason they are doing DaiRanger is because they are out on DVD in Japan. ZyuRanger will not be out until Sept.
I think many people who are used to the newer shows, are more negative towards fillers. And we have to agree that many of the old shows had tons of filler material. There were some extremely good episode arcs, and there were all the filler episodes that made up a good chunk of the series.
I disagree, as they are the same. Hell, DekaRanger was nothing but filler. There was not a single episode that did anything of a continuous story. Shows like KakuRanger, Liveman, Jetman, CarRanger, all have filler episodes, but most of the episodes were enjoyable nonetheless. Take KakuRanger for example. Even its worst episode (the one with the narrator guy that documents the Hana Ninjas) is better than 90% of the filler episodes from the Sentai series in the last 10 years. However, DaiRanger is 90% story arcs and 10% filler. Not to mention is the best Sentai, or Toku, ever made.
Some people are just not used to the old super-hero format. They want an ongoing story with drama that leaves them with a cliff-hanger every second episode.
I agree in the case of Kamen Rider. Black is my fourth favorite Rider show, but I prefer the continuous arcs of Kiva, Blade, and Ryuki over Black's formulaic process.
Though, it seems that there is a growing interest to see the Metal hero shows subbed. I think if someone started doing a Metalder or Janperson project, then it would gain a lot of interest.
I want the B-Fighter series subbed. I bought all five DVDs of B-Fighter Kabuto and I would love to see it subbed. A great show that was royally ****ed over in the states.
