The show has never disappointed me through the years. Though I know people need to leave the show for whatever their reason, they have always delivered the same quality in the the show.. I will more than likely never stop watching this show not only for the drama it brings but also the characters themselves.

I LOVE CSI! With the series being led and produced by Billy Petersen it makes for a winning formula. Well acted, well written, and we'll directed, CSI was (and still is as far as I'm concerned) one of the GREATEST shows on CBS. Unlike other procedural shows typically dealing with the legal side of crime, CSI offers a forensic approach, making for a fresh take on an overdone concept.

Like life, all good things come to an end. People move onto other things. Plus you can only do so many story lines before they start repeating themselves.
