My really (and serious) first thought about Super Sentai

I was 9 years old (2006) when I watch Gaoranger vs Super Sentai (my first Sentai video) by accident. And I thought at first that Super Sentai must be a parody or rip-off of Power Rangers. When I look up about Super Sentai website. I immediate laugh at them because the way they did to Doggie Kruger's head. It look like a puppet. But I realize that Super Sentai is not a rip off or parody. Super Sentai was actually a source for Power Rangers idea.

What is your first thought about Super Sentai?
