Oh. Okay, I see what you mean. My bad. :o

Yeah, precisely this. It's got a great ending, but it's also very much a "the story goes on and on" kind of ending.

Gokaiger

Gokaiger comes closest. I wouldn't have said no to continuing longer and making Legacy episodes (and maybe mecha) for every series. That said, I'd still want it to end. One of the appeals to Japanese media to me is that almost everything gets an ending. I hate when a show has been on for years and then just stops or ends on a cliffhanger.

I agree with every statement made by Blade Raider above.

I loved loved loved the cast of Gokaiger. They had a cynical, slacker, punk rock attitude but were still good-hearted, genuine heroes. I could watch that cast forever, and for me the cast is what defines a sentai show more than anything.

A similarly great cast, one that approaches the idea of sentai with the exact opposite sentiment of the Gokaigers, are the Kyoryugers. They unabashedly embrace the idea of sentai and all its silly tropes with a near-zealous brio, but are equally charming and fun to watch.

In fact, more than anything I'd love a team up series between Gokaiger and Kyoryuger. Their diametrically opposed attitudes toward being a sentai would generate some interesting conflicts.

But that said, no story can go on indefinitely, and generally I prefer the way Japan handles a story by making it utterly finite.

Tensou Sentai Goseiger. Not the whole series. I would just love one more movie as Epic has Goseiger v Shinkenger, with Brajira making a triumphant return.

Gekiranger was already perfect. Making it go on would give it the same issue so many series suffer today. It would tarnish perfection by becoming a farce of what it once was.

So, if there was one series that I wish would've continued, it'd have to be Kakuranger. I haven't seen past episode 10 or something, but screw it. I love it so much that, if I were the Toei exec, I would've cleared it for a season 2 at that point :p

I'd settle for another Ninja season period.

It almost did, actually. There was a serious proposal for a second season of Dekaranger, but Toei ultimately decided to stick with the existing pattern.

But yeah, I'd pick Dekaranger, too. That show was great and it could honestly still be running today as some kind of weird tokusatsu/police procedural hybrid.

Also, I want more Umeko.

In the meantime, we've gotten Samurai and Pirates, so sure. Why not? :p

Dekaranger would be a neat season to have a sequel for, but I don't know if it'd be necessary, especially given the ending.
