Having watched this series from the pilot episode, I've not missed one episode. I have them all on videotape, and now that they've been released on DVD, all the better! I have all 3 seasons, and can't wait until season 4 is released. This is a fantastic show with realistic crime scene depictions, often taken off the front pages of today's newspapers. The twists and turns make it fun to try to solve the crime before it shows you at the end, and some cases I find truly baffling! The tools are real, and I've gotten to the point I have a deep interest in forensic science. I've even thought of going back to school for it because of this TV SHOW! I think this is my favorite show EVER..even above ER, Third Watch, and Crossing Jordan! If you haven't seen it yet, you're missing something truly unique! Furthermore, I like the original CSI in the Las Vegas setting, and don't much care for the spinoff of CSI: Miami. CSI: New York is beginning in the fall, and I'll give that a couple episodes before I decide. I'm a CSI fanatic, I can't help it!
