Why have the slam dunk contents sucked since 2000?

I remember the 2000 slam dunk contest, at all-star weekedn in oakland with vince carter, I was 10 years old at the time, and it was one of the most amazing things I had ever seen. Vince Carter put on an unforgettable performance, that to this day I can't believe. But honestly it seems like they dunk contents have flat out sucked since then. I don't know if Vince set my standards way too high as a young kid, but wouldn't you agree since 2000 no one can match that slam dunk contest?
