Well, after seeing that trailer, I gotta say... I'm on the fence about it.
Considering it's Power Rangers, I guess it makes sense they'd use a redesign of the ZyuRanger suits. To me, that's the one thing that kind of keeps me from wanting to support this. I would have preferred if, instead of some rebooted origins story, they had just went 100% original with nothing at all borrowed from Japan. But all in all, it's not bad. This is definitely as close as we're going to get as far as Saban making their own thing and having Power Rangers evolve into its own thing. It actually reminds me of what happened back in the day. Toei had offered to make their own original suits and Zords just for Power Rangers (I think there are scans of Toei's promotional art work for this floating around on the internet somewhere), but Saban turned them down because adapting the all ready existing footage was easier than paying for a collaboration. It's nice to see the idea of being something unique wasn't completely phased out after all these years.
