Fun fact: Sentai is aimed at preschoolers, not middle school kids.

One of my favorite anecdotes from a friend of mine who worked as a teacher in Japan was that by the time a kid was in the 4th grade, they were too old for "kiddy stuff" like Sentai and Kamen Rider and were watching shows like One Piece and Pokemon.

So like what you like, especially as an adult, life's too short to let people make you feel like crap for something you take genuine enjoyment in.

If your friends are in nerd fandom, don't let them give you shit, you're all nerds. Hell, even if they're not, real friends probably wouldn't give you shit for what you like.
