As in, what's something you loved as a kid, found cringe as you get older, then gained a new appreciation for as an adult? Here are some of mine:
- Pokemon. I expect this will be a common one. It's got cute creature designs and fun tactical battling, and since I've outgrown my shame at liking cute things, I'll happily keep coming back to it.
- Yu-Gi-Oh. I still don't much care for the CCG (I'm opposed on principle to any game where your ability to win largely depends on how much money you're willing to sink into it), but the anime bursts with dorky charm and the video games are fun. A setting where reincarnated ancient sorcerers and billionaires are stone-dead serious about a children's card game is also a nice break from the modern plague of "well that just happened" Marvel soy banter.
Skrillex or dubstep in general
I was a Skrillex hater when he first got popular and it was cool to hate on "brostep" or whatever. but since then I've realized the guy is really talented. Quest for Fire was one of my favorite albums of last year. his early music is still probably not for me, but that doesn't mean it's bad, it's just a matter of personal taste
