I've only seen a bit of it but it was pretty damn funny. Some folks I know were offended by it but it seemed like all jokes to me lol. I haven't been able to watch Akibaranger yet being that I've finally started to watch a bunch of other Super Sentai but I'll get to it after I finish Magiranger. I'm dying to see the Chinaman/Dairanger episode though... I downloaded a clip with their interpretation of Dairanger's opening and can't stop laughing whenever I see it.
I wanted to cosplay the Red Powerful Ranger but I don't think anyone up here would get it >_<
You should do it for shits and giggles. As for the episode, I saw it as more of the writers making fun at their "interpitation" of Americans and not making fun of Americans. I really wish there was a clip on Youtube.
