most of them were successful. its just that series outside of power rangers(beeteleborgs, vr troopers and even masked rider) the others had runs coming to an end so they didnt have anything else to work with(or with beetleborgs, the shyt got even kiddier to work with)One of my favs too as a kid. Saban was trying milk the shyt out of those tokusatsu franchises here in America. Some were successful and some were flops.
