Cause:Toy sales are terrible and show is terrible(Go-busters)
Effect- A safe by the numbers series(Kyoryuger) with a sure fire hit merchandise gimmick( Dinosaurs)
Kyoryu's batteries and dinosaurs theme was decided even Gobus even aired. It was decided close to the end of Gokai and likely as a result of how well the Rangerkeys did.
The trains will sell. C'mon they're trains!
I disagree. It's not the theme that is selling the merchandise. IMO it's the collectability element ported over from the Rider franchise that is helping move the merchandise. Gobus's combination of lack of collectible gimmick and boring show was what killed it.
