I loved CSI: Las Vegas when Grissom and Warrick were on. I understand they had to do "something" with Warrick when he left but did it have o be so harsh? And Grissom, noble that he left to be with Sarah but come on. They have not fulfilled nor done him justice by replacing him with Fishbourne. I miss the intellect and charisma of Grissom - he was perfect for this role. I think for this show to survive they will have to build around Nick and Brass. Afteall, Grissom did groom Nick.
