Are sentai buried to the minds of the Filipinos?

I went to 2 cosplay conventions and I found out some people doesn't know sentai only appreciated those rip-offs also called power rangers,the only worse is another series will follow to continue another brainwashing moment. Majority of otaku fans here in the Philippines were only stick to Naruto or any longest running anime series without any feeling for themselves on what happen to live-action series here in Japan,Dragon knight still invading toysales what's next ??
