Five stars for CSI: Vegas, one star apiece for CSI's:Miami and NY. The main characters in CSI:Vegas have a chemistry that keeps even the slower shows going at a decent pace. The rivalry between Nick and Warrick, the tension between Sara and Grissom make the main characters almost as much fun as the various murders do. While the science may not be 100% factual, I believe it's real enough to be fascinatiing (I believe they mostly exaggerate how fast they can do things), and some of the mysteries they've solved were just fascinating. That, and the fact that some of the episodes are taken from the headlines of today....all in all, an excellent show.
