So what? Completely different franchises and it should stay that way.

So?

Without Spider-man, there'd be no Super Sentai. Without Daredevil, there'd be no Ninja Turtles. Without half of DC's main heroes, there'd be no Watchmen. Without Microman and Diaclone, there'd be no Transformers. Do all these things need to pay homage to those that preceeded them all the time? No. Especially when the relations are superficial at best.

There's no point in referencing Sentai when most Sentai fans would probably just be upset by it, and most people wouldn't even get it. Just keep them seperate. Power Rangers was envisioned as being entirely seperate from the Sentai it "adapted." Wouldn't it make more sense to stay true to that idea rather than needlessly reference irrelevant details?

I can always count on Split to drop in and be the only voice of reason in these kinds of discussions.
