To start with, I really, really like CSI. To the point where I'm almost killing the store clerks if they haven't got the one I want in stock. I'm almost a crime scene myself. If you don't like CSI or have never heard of it before, try and watch one episode, particularly of the third season, and see if it makes a difference. The third season of CSI is the most intriguing one out of the four that have been released. Better than the previous two and the fourth (what is up with William Peterson's beard?), it is definitely the one to buy. There are 23 episodes, which ids good value for money. The extra features, whilst not numerous, are interesting and will hold your attention easily for the time that they are on, probably because they are so short. That is my only complaint though. With some excellent episodes and a revisit to Lady Heather's, one of the highlights of Season Two, this season is really the one to buy. I particularly enjoyed the episode 'A little murder', concerning the murder of a dwarf in a Las Vegas convention. Clever and funny without being cruel, it was excellent. Similarly, the episode 'Blood Lust' was very good. A teenager is run over and the mob who are watching innocently from the bar across the road believe he is going to drive off when, in fact, he is reaching for his radio to call the police. When they kill the man, they are all suspects for his murder. An interesting episode that clearly shows the sheen and class of CSI that makes it just that little bit better than NY and Miami, i highly advise you to buy this. Really, I advise you to buy it.
