But for me, it's not just about nostalgia. it's about what I think still works for me. There are a lot of things I look towards with nostalgia, like Captain planet and such, but I just can't stand anymore. I used to love Care Bears when I was in preschool... it was so....colorful... but now I really dislike them.
As for some other things, I still think they are worth merit. I still enjoy things that i can get back into, Like Darkwing Duck, The Tick, and various others like that. Something I loved as a kid, but I can still find as funny, or funnier. No better example is Rocky and Bullwinkle, which keeps getting funnier the more I understand the jokes.
Years and years ago, I was in History class, and I came across a passage from The Rubaiyat of Omar Kayam. And I just laughed my head off for five minutes.
