Perhaps at first glance it's obvious to compare Kakuranger with Hurricanger, but these are actually two very different series:
Kakuranger is purely inspired by the ninja theme.
Hurricanger on the other hand is a show that takes a lot of elements from Kabuki theater. Of course, there are some ninja elements in it too (just like we find ninja/samurai references in Kabuki theater), but I always felt that Hurricanger was first and foremost a Kabuki-themed sentai.
As such, I have to put both shows on equal foot, considering they are different shows with different premises, each one being good at what they try to be or try to reflect.
