About the only things I liked as a kid that I legit find hard to go back to are educational games like Sesame Street 123 for the NES. But that's a specific circumstance for a product that served a very niche function, and even then some educational media holds up or even gets better with age--the cartoon Where on Earth is Carmen Sandiego? (the 1990s one) for example.
Do I sometimes revisit stuff I liked as a kid and find its no longer perfect? Yes actually--Teenage Mutant Ninja Turtles used to be a huge part of my life but these days I'm not as big a fan (though I still like it). But being less-than-perfect doesn't mean I suddenly hate it. And besides, usually what happens is the position has been filled by something I kinda-sorta knew about but didn't pay attention to as a kid (just for an example, as a kid I didn't like Transformers at all, now I'm a fan of G1 and even kinda like Challenge of the Gobots).
Video games are a funny thing as an adult. As a kid I remember thinking a lot of them were hard, borderline impossible. I imagine a lot of people had this experience because you still to this day hear the myth that NES games were stupid hard.... in reality though, most of them are easy, you were just a stupid kid.
This makes video games weird though. Some of them are legit way better than when I played them as a kid because I actually know what I'm doing and I'm not constantly dying on the first level anymore. Others though are less fun precisely because of this and because I'm aware of the shortcomings--as a kid, having to visit the Transylvania level in Ducktales three times never bugged me, but as an adult I find it a bit repetitive.
.... TL;DR
Growing up didn't result in a "I hate everything I used to like" reaction, it more just resulted in a re-balancing of where I would place things on a tier list.
