"What I do know, my friends, is that I am almost dead..."
Like magic - crime is solved by putting hands on hips & adjusting shades, all under the orange filter sky. Yes - "Miami" is the worst of them...
Any show that remains on the air will see a turnover in cast. Actors wouldn't be actors if they didn't want the chance to act in many roles. Eventually they all want to leave to accept other offers.
But personally, I would have continued watching the show if they hadn't kept increasing the amount of close-up CG gore shots, and hadn't tried to parlay acting chemistry into romantic chemistry. If I want to watch a romance, I'll tune into a romance. Forcing skin and tongue into a scene that the actors could very well carry on their own without that aspect is a real turn off to me.

Turnover is inevitable I agree.
But with CSI - its largely all happened in the last 2 seasons - Warwick, Sara now the Great Man himself. I don't care who they bring in to replace him - NO ONE can bring what Petersen has brought to that role.

I admit to never having survived watching an entire episode.
I can stand a few minutes, if only because of the brilliant cinematography, very compelling in HD.
But the entire premise is retarded. Forensics investigators are worker drones on crime scenes. They do not lead the investigation, they do what they are told to do by the police. They do not interview suspects, they do not speak to criminals.
I actually prefer CSI New York - probably because of the New York backdrop but also it just doesn't seem as tired as CSI (original).
And, CSI Miami is great to simply take the mickey out of. I know there are CSI Miami drinking games at university - how often David Caruso pauses and looks seriously at something, males wearing white to a crime scene, females wearing white to a crime scene, number of times they focus on their blackberry/pda, etc etc.
'tis great.
