You know, I never really thought about it as an environment, but reading about the 80s cartoon nostalgia just made me realize how much "my" room is set in the 80s and early 90s. I have my posters & toys from Labyrinth, The Last Unicorn, and Legend, and most of the decor is very much like I wished my room was when I was a child. I wouldn't want my whole house done that way, but it could be why it is such a nice refuge when I want a break from the day to day adult drudgery.
I still watch some of the old cartoon/kid's movies on occasion, and think many of them were much better than the crap that's on now. It really ticks me off when they take something that was cute and a childhood icon (Rainbow Brite, My Little Pony, Strawberry Shortcake), and "update" it to try to appeal more to a new generation (which apparently likes their cartoon characters thinner, more grown up, and slightly skanky, rather than just cute).
