OK, I confess, I am a serious Voltron (lions) fan. I even saved my pennies as a kid and bought the large lion set, the one where the assembled Voltron stood almost three feet tall. I saw, I think, two of the vehicle episodes and didn’t care for them, but the classic? Oh yeah!
Interesting that Voltron uses a Japanese blade-work style, but not surprising. Granted, when you are using a broadsword, parry-and-thrust is not really within your style book.
Cheesy? Yup. Repetitive? Yup. Much fun because the good guys win and the girl is not just a sidekick to be defended? Yup.
Would I love more backstory? Oh heck yeah. Where did the tech for the robots come from, who built them, how, why, why did they get divided up (see the movie), how did the king’s ghost get built into the lions . . .
