Ch-ch-ch-changes: Eric Bogosian replaces Jamey Sheridan as the detectives' boss. Annabella Sciorra is gone, and Julianne Nicholson is Chris Noth's new partner; Courtney B. Vance is out, with Theresa Randle (Bad Boys) in for at least three episodes. One constant: Noth (Det. Mike Logan) and Vincent D'Onofrio (Det. Robert Goren) will still alternate as the investigators. C'mon, new showrunner Warren Leight, give us a ripped-from-the-headlines plot. ''You know those teachers who stray with young male students? One of those leads to a murder. [It's about] what goes on in someone's head that causes them to fall in love with a student, when she crosses that line.''
