I dunno. I think I said this once before, but an animated series has some potential. I mean, with an animated series, they would have the freedom to use all sorts of characters from past or present, as well as old mecha, without having to worry about footage. They could bring back all of the old rangers and villains and not worry about hiring back the old actors and what have you.
Still, half the charm of "Tokusatsu Hero" programming is that it's live action. As it is now, Power Rangers is currently one of a kind in the States. I would hate to see it become just another cartoon.
