RZA was humble, but he was a wild dude like the rest of them. He was in and out the system just like Divine. I thought the actor was questionable at first, and them wanting to show the quiet one, to contrast with the other personalities, and he'd grow into the RZA, but now it is really starting to bother me. He's really holding everything back, especially since the others like Shameik & Dave East are really becoming their characters. He's also not coming across as intelligent as RZA is. RZA really has genius level intellect. The thing is that it's all there, he's just not doing it. Hell, every time Sha is on screen, he looks to be scheming on something/someone...just like Rae. It's hilarious.
Divine still leading the pack, but Sha is gaining on him as far as best portrayal. Dirty is next, with Meth coming up. Ghost is a good actor, but it's just not Ghost. GZA is OK, we haven't seen enough of Deck.
