Just watching through it on YouTube and it's hard to watch.
I mean, watch this http://www.youtube.com/watch?v=z-BeXwXs-po from 5:17 onwards when he's "rapping" (I use that loosely) Evil Deeds, it's horrible - just that zombie look from the drugs, it's creepy as fuck and damn saddening.
The whole show was horrible as fuck, a zombified Eminem mumbling his worst songs and a murdering a few classics. I find it amazing that people even try to claim the drugs played little effect in the Encore era.
To think the genius of 1997-2002 could turn into the horrible rapper/perfomer/person that we saw in the 03-08 drug phase shows how fucking powerful addiction is. Scary.
