[Sentai]

I see a major problem with the Legend War. Aside from I don't want it right now, Gosei deserves a full season, and Saban screwed me once again. ... Ahem. It's, to put it simply, the actors.

Alot of them got old. And not in the dignafied japanese way. More in the "OMFG Have you seen Andros?!" way. And alot of them, for whatever reason, just won't come back. Power Rangers isn't seem as in the same light here as Sentai is in Japan. And that's a shame.
Who was the actress in Lost Galaxy that did that movie that's softcore porn without being softcore porn? I doubt she's coming back. Amy Jo Johnson pretty much distanced herself from anything MMPR since the Turbo movie. Jason David Frank'll come back again and again, and we love him for that.
But what about the rest of the original MMPR cast? Johnny Young Bosch'll come back. I believe he will, Ichigo wouldn't let me down. We tragically lost Trini's actress. And I don't think we need the bland blah of Aisha.

That's what I think is going to drag the Legend War down alot. It's limited by how many past actors they can get to return for what they need storywise. And that's going to be a serious uphill battle.
