Hmm. Its between Ghosts and Smooth Criminal for me. The choreography for Ghosts is intricate and detailed and Michael makes it look so easy. But Smooth Criminal's choreography is so.....smooth lol and cool and that video was pure genius from beginning to end. So, I'll go with Smooth Criminal with Ghosts as a close second and YRMW in third. Oh and Bad in fourth lol.
I'd have to definitely say...the Panther vid. Yes, I know it wasn't a music vid per se, but I believe it used to be part of Black or White, didn't it? I adore the dancing he does in that video.
But its not choreographed.
