The last thing I expected to see on CSI was Black Sabbath. Yes, THAT Black Sabbath, with Ozzy, Tony and Geezer in full force, tearing it up as they opened the episode. It was actually damn cool. There are a lot of guest stars in this one. Well, 'stars' that were once big and have since faded from the lime light. Eric Roberts, James Callis, Annabella Sciorra and Tim Matheson make up the bulk of this episode that follows closely with Se7en as a serial killer is on the loose. Pretty good cliffhanger as it all but guarantees that I will have to tune in next season to see the fate of Morgan.
