interesting gen on the alternating Law & Order: Criminal Intent casts: I enjoy them both, myself--

"D'Onofrio's overheated, scene-hogging style couldn't be a sharper contrast with the cool, sly suavity of Chris Noth. Det. Mike Logan is a throwback to an older school of TV cop, less Gil Grissom than Jim Rockford; he gives the impression not only of having a life outside work, but of occasionally phoning it in at the job so he can get back to the fun stuff."
