I cant really put it down to being all terrible. As there are good bits and bad bits!
I base my years on a few things. Quality of wrestling, love life, music, weather, school.
For me:
2000: was a great year and I actually really liked all the music that year. Summer was amazing if I remember correctly. (I was only 9 at the time) and Christmas was great as I got my brand new PS2
haha
2001: was quite good apart from 9/11. Summer was amazing as usual, I was a big fan of the music that year also. Mike released Invincible.
2002: was pretty bad imo. I moved on to high school and the first year is allways terrible, music was still quite good but was getting worse. Summer was terrible if I remember correctly.
2003: Was a great year for me. I enjoyed the music, summer was actually pretty good! I would say that the accusations against Michael let the year down, however I wasnt particularly a fan at the time. School was actually damn good that year!
2004: again this was quite a good year. Not as good as 2003 though. Wasnt much good music at all this year. Maroon 5 were the best thing about this year for me music wise. School was great still.
2005: I found 2005 to be pretty bad actually. With the trial and the summer was terrible that year. Music was pretty bad and was probably my worst year in school ever!
2006: Loved 2006! Loved a lot of the music and the summer was great! It was also the year that my love life actually sort of...started :S I fell for some girl but she ended up with my best friend, which wasnt too good. But it doesnt let down the year! The WMA with MJ was great as well!
2007: This was pretty bad I think. Summer was terrible, music was even worse. A terrible year for wrestling with the Christ Benoit double murder suicide incident. We saw a bit of Michael but that was it. Just a dull year really :\ I got my first gf which was good, however it didnt last long. I got my 2nd gf the end of that year!
2008: 2008 IMO was pretty damn good! I was with my 2nd gf all that year and it was amazing to share so many good times with her. Wrestling was ok that year. Music wasnt too good really but meh....
2009: WORST YEAR EVER. Celebrities died left and right. Especially Michael dieing was the biggest blow. The first 3 months were great! I was still with my gf and Michael announced he was doing his 02 shows! Everything was going amazingly. However then my girlfriend left me and went out with someone else, and then MJ passed away. :\ Its been absolutely horrible, the music seems even worse now that we dont have Michael. Just a terrible terrible year.
So yeah, thats it.
I give the decade a 6/10......maybe even 5.
