Hey Black Fang, I hope you don't mind if I hijack your thread for a quick question of my own, but I'm actually rewatching it myself, and I was reminded of something that bugged me when I first watched it.
In episode 5 of the second season, Akagi remarks about how he "was probably too old" to do something regarding Zyuranger. Now, while in the first season, they make light of how he's 29 and still in Sentai a few times... Zyuranger aired over twenty years prior to this comment being made. At the absolute worst, unless I'm misunderstanding what it was he was waiting in line for, he would have only been 10.
Was this just a poke at how kids at that age feel they're "too old" for certain things, and how it's "not cool" anymore? Or in Japan, are you really considered "too old" at just 10 to still like Sentai? I get it might be the latter given how important it is to fit in and all of that, but it stood out to me the first time I saw it and it does again now.
