CSI: NY (CBS)
After beating back death for two seasons, the third show in CBS' CSI franchise cracked its last case. (Ironically, the original CSI keeps going strong.) Always more grounded than its Miami sister, CSI: NY mixed its scientific crime-solving with interesting stories about New York itself. And even more than the other shows in the franchise, we believed this team was a close-knit family — and not just because Danny and Lindsay got married. Perhaps reading the writing on the wall, the show closed on a very conclusive note: Years after losing his wife in the 9/11 terrorist attacks, Mac proposed to his new love Christine. Who doesn't love a happy ending.
