Eh, I think the Zyuranger monsters are pretty great as it is.

some of them maybe.

Why Toei reuse the same cockpit from GoGo-V in Goseiger ?

I can't agree with this at all, Zyuranger has some awesome designs. They look a lot more modern than some of the other designs from that era.

They didn't. Why the hell would you come to that conclusion? The shows are 12 years apart!

Goseiger could have been better without the cards ?

The cards weren't Goseiger's problem.

Could have been like Gingaman but without the cards.

You don't understand.
Removing the cards does not change much anything at all. It merely changes how the action works. It would not be like Gingaman just because Alata isn't inserting a card to shoot a fireball.

You need to change a lot more than just the gimmick to make a series more resemble another show. This is akin to saying Ninninger would be more like Kakuranger if they removed the shuriken.

Yusuke Okada is not the current president and ceo of Toei ?
