Part of what made Margos so appealing to me was how everybody around him reacted. Dutch, Vic, Danny, Acevada, his henchmen. You knew that this guy was an evil soul without him saying a single english word.
I haven't seen all of Season Four, however, so my opinion regarding Andersons performance might change.
When the fuck is David Rees Snell going to get promoted to fulltime cast member? I mean, the dude has been around since Day One and is still considered a fucking guest star. Ronnie WILL be recognized goddamnit.
