I really can't blame Saban for this decision, in all honestly.
You do realize, Toei/Bandai still have control of whether to give Saban ANY Sentai footage or not. If Toei/Bandai are still upset over the utter disappointment of Go-Busters from both a tv and toy sales standpoint, of course they wouldn't think about giving Saban any footage of the Go-Busters show EVEN if Saban asked for it.
If anything, it shows how much Toei and Bandai are still a bunch of butthurt bitches over the fact that Japanese children couldn't find anything appealing about Go-Busters AND they don't want to waste another single ounce of money to continue investing in any Go-Busters project........EVEN as a US adaptation.
So basically this wasn't Saban's decision at all, this was Bandai's decision with Toei backing them up to not giving the Western audience a Go-Busters adaptation of Power Rangers
You can continue to scream and shout at Saban all you want........but Bandai & Toei are the real culprits behind this decision.
