I think more people need to realise that if Saban had the time and money (which he probably does...I'd also factor in the existence of toys but BOA just make their own these days) we would probably get a completely original Power Rangers series. However, it's much cheaper and easier for Saban to use the existing footage in whatever way he and his team desire, thus the formula of importing sticks. That and a pre-installed fan base of people that followed the sentai but couldn't afford the merch. Look how quick people snapped up Megaforce stuff, I can guarantee not a lot of it would be by kids.

It's basically a mixture of being cheap, lazy and (sometimes) trying to tell an original story, yet still fit the existing footage. Im by no means saying this is bad, its obviusly good buisness, but Saban could obviously do so much more. It's a formula started by the 1956 Godzilla film for marvelous' sake.

TL/DR: If you want Gosieger or Gokaiger you have the knowledge and the means to acquire it and watch it.
