Lol, i can't bring myself to watch Zyuranger because of how much i hated MMPR.
MMPR has as much to do with Zyuranger as Prince Dex does with Minami Kotaro.
me personally, when i find a season too slow or just bad, i like the opposite much more. Magi ranger was too cutesy for me, MysticForce kicked ass. Hurricanger was too slow, Ninja strom was full of energy, Operation OverDrive was operation overDrive, BokenRed and Silver became some of my favorite senshi's. (Genta fan girl)
Did you try the first episode of Zyu at least? :3
