Every list of things from the 90s that are "the greatest" are just things that you miss from your childhood. Everybody misses things from their childhood, when responsibilities were minimal and things were simpler. If Buzzfeed existed in the 19th century it would be filled stuff like "21 Things from the 1790s That Were Totally On Point" or "16 Toys That Rocked it Before the Industrial Revolution". So the 90s weren't the best - childhood was.

Added point: the 90s didn't have Smartphones. You couldn't Facebook stalk your crush at a party to find something to talk to her/him about. You couldn't immediately go on Wikipedia to find out Delaware's state flower and settle an argument. Most importantly, you couldn't read Buzzfeed on the toilet while you pooped. How good do the 90s sound now?
