L.A. Law (1986–1994)

This was a seminal show -- probably the first "lawyer show" that wasn't really a detective program in disguise. L.A. Law introduced us to many of the particulars of a law firm: The staff meeting, administrative hearings, appellate court argument, as well as almost all aspects of criminal and CIVIL litigation. It was an amazing program that, when it focused on the intriguing cases that came to the firm, was arguably the best show on television in the late 80s and early 90s. If I recall correctly only Hill Street Blues, The West Wing, and L.A. Law won 4 Emmys for best drama (now maybe Mad Men?). There's a reason this show ranks in the upper echelon of television dramas.

To be fair to its critics, however, I can't remember ANY program that was this good that, almost abruptly, became so bad! Although I continued to watch it until the end, it was hit-and-miss at best, and sometimes just plain terrible after the fifth season.
