The Legacies of "24," "Law & Order," "Lost"?

Kansas City Star TV critic Aaron Barnhart, a guest on our show today, looks at the three big "defining dramas" that are bowing out from the television stage. "24," "Lost," and "Law & Order" will all wrap up their runs within a day of one another. What do you think of Barnhart's views, from his article "Three Defining Dramas Bow Out"?

On "24"'s meaning:
Barnhart: Whether those were apocryphal or not, it’s hard to think of a TV show in the post-9/11 era that has resonated politically more than “24” — not “West Wing,” not even (I hate to say this) “60 Minutes.”
 
On "Law & Order"'s importance:
 
Barnhart: It’s hard to think of any TV event in my generation that matches the departure of “Law & Order.” The show leaves behind three offspring, including the new Los Angeles-based version NBC picked up for the fall. But the demise of mother “L&O” closes the book on a certain kind of story-centric crime drama that flourished in the 1990s...
On "Lost"'s impact:
Barnhart: Serial dramas are a major commitment for a viewer, and unless TV networks stop making them, there will always be too many to watch...Like it or not, then, the show that will endure is TV’s defining procedural, the one that requires no previous knowledge or experience the moment you dial it up on your DVR or computer or wristwatch.

Do you agree?
