...is "Law & Order: Criminal Intent."
I'm not a big fan of police procedurals (never seen "CSI"; used to watch the original "Law and Order" and "SVU" but eventually abandoned them), but "Criminal Intent" should appeal to anyone looking for great writing and storytelling on television. I expected the worst from newcomer Jeff Goldblum, whose Det. Nichols replaced franchise favorite Det. Logan (Chris Noth) in the recently-concluded 8th season. But Goldblum has created another idiosynchratic detective akin to D'Onofrio's Goren. Also, "Criminal Intent" finds intriguing ways to tell its ripped-from-the-headlines stories (unlike in later seasons of the flagship "L & O").
I highly recommend you catch this show on re-runs during the remainder of the summer. Season 9 won't begin on USA Network until next spring, but you can catch re-runs throughout August (here's the schedule). It'll help you get through the 6 week TV/movie doldrums between now and the start of the new Broadcast TV season (9/21).
