“CSI” — Seventh Season
The seventh season of “CSI: Crime Scene Investigation” is as solid as any of the series’ previous years. The stories are strong, the actors share potent chemistry, and the characters are believable because they are flawed human beings. This year, “CSI” delves into the complicated romance between head investigator Gil Grissom (William Petersen) and his underling Sara Sidle (Jorga Fox). The two are reticent to let their colleagues in on their relationship, and the season finale offers a gasp-inducing prospect of their future together.
