I can get not liking the 90s because they sucked for you personally (and hey as a geek 90s teenager I totally understand), but objectively looking at the decade the 90s kicks the crap out of the 00s. We had hope and innovation; it was when the 'net first started taking off, computers started being able to do more then display text and clunky bitmaps, it was the 90s that saw the fall of the USSR, it was the 90s that showed promise with peace accords all over the world (that fell apart of course, for the most part at least, but at least it was looking like good), sure there were things that sucked about the 90s (a lot of the music for one, some horrible wars in Africa and Europe) but compared to how the 00s "the dawn of a new millian" it was a golden age.
I spent most of the 00s in a constant state of depression about how bloody horrible the world was getting, wars, terrorism, reality tv, stock market crashes, economic crises, Michael Bay movies, etc. etc.
So yea, I think that's my issue with the "90s sucked" image. You're totally correct that the 80s however are the best decade.
