The negative aspect of the Legendary Battle.

They can't choose the shows theme, they have to follow the sentai. And Judd Lynn is now back in charge, and he helmed some of the best seasons of the show, so Dino Charge can only be good. The reason the Legendary battle has a negative aspect around is because the rest of Megaforce/Super Megaforce is a pile of dog sh*t, and there's no reason the final is any different (which it isn't, having watched it).
