"Law & Order" (9 p.m. Central Monday on NBC)
On air: 1990-2010, 20 seasons
Why it was great: It ripped about one-third of its stories from the headlines. I'm not a big news-watcher -- I find it depressing -- but I am a big entertainment guy, so when I can be entertained and keep up with current issues by accident, that's cool. Watching the detectives and prosecutors at work drove home the thrill and the value of doing something important with your life.
Between Hulu and DVRs, it's easier than ever to watch current TV shows. And since NBC wiped out five hours of programming with its Jay Leno show, and The CW axed its Sunday slots, the schedule is thinner than ever.
So you'd think the shows that do exist would be easy to watch. Yet I feel like "Law & Order" (7 p.m. Central Fridays on NBC) has fallen through the cracks.
