It remains my favourite of the LAW & ORDER shows!!

‘Law and Order: Criminal Intent’: Is series finale the end for Vincent D’Onofrio and Kathryn Erbe?
Vincent D’Onofrio and Kathryn Erbe, as detectives Robert Goren and Alexandra Eames, solve their last crime together Sunday (June 26) — or the last one we’ll see as viewers — when the the “Law and Order: Criminal Intent” series finale airs.
D’Onofrio and Erbe returned for the show’s 10th and final season, after sitting out season nine. Juli Ormond also signed on for season 10, playing the police psychiatrist of which D’Onofrio’s character, Goren, was in dire need.
In the finale, the story is ripped from the headlines. We won’t get into specifics, but let’s just say if you saw “The Social Network,” you won’t have any trouble following the action. The story is helped along by James Van Der Beek, who guest stars as a cocky businessman who mainly holds court in night clubs surrounded by what appear to be paid escorts. 
And, who knows, the show may have some life left in it yet. 
“I know that I would be there in a heartbeat,” Erbe tells when asked if she’d re-up for an 11th season. “I’m fairly positive that Vincent feels the same way. Everyone was really hoping that, in the 11th hour, we’d get some word. Whether the fans are able to muscle us back or not, who knows. They have amazing power.”
“Law and Order: Criminal Intent” airs Sunday (June 26) at 9 p.m. ET.
