For what it's worth, I hadn't watched any 'power rangers' in years and randomly decided to watch the newest series that started in Japan this year.

It's pretty cool. They've gone back to the 'chanbara' style of old samurai shows, while still giving it the 'sentai' cheese of today. The ground combat is pretty exciting to watch, before they go all super power and use their big dumb robot. Fight choreography has usually been one of the stronger points of these shows. Appare!
