My two cents on season 2, it was a lot more exciting than season 1, because they’ve incorporated more science and music into the series. Also it’s more entertaining than season 1, although there were some good season 1 episode.
Some quick highlights
We learn more about Grissom’s ways, like when he would ignore his fellow CSI’s it becomes evident in the season 2 finale
Also we see more of the CSI’s personal life also Paul Milander was carrier over from season 1.
What I love about season 2 is “Cross Jurisdictions” where we are introduced to CSI Miami. I think more shows with spin offs should walk in CSI’s path.
This is about as good as I remember, I watched the DVD’s over a few days during Christmas break.
Now I’m waiting for Season 3 to come out but I’ve got that covered
