I'm not sure, actually. I've only gotten through episode 4 myself. I could have sworn I saw up through 26 at least, but I could be wrong. I'll let you know.

And really? More lighthearted? I hesitate to say that. I wouldn't call Zyuranger darker because, let's face it, they're both relatively silly kids' shows, but considering that MMPR has zany teen problems and two ineffectual bullies while Zyuranger's heroes are ancient warriors, I find it hard to say that Zyuranger is lighter. But I guess that's all just opinion.

And as far as the music, I find Zyuranger's music to generally be more epic-sounding, while Power Rangers goes for that hard-edged but static electric guitar music that would get passed on to the DBZ dub (makes sense since Shuki Levy did the music for both). The Zyuranger ending theme is certainly wacky, though. It cracks me up. I like the concept of the warriors attempting to fit into the modern world, and I hope that actually becomes a plot point later rather than just being the source of gags over the end credits since I haven't seen much of a chance for these characters to really show who they are yet in the four episodes I've seen.
