In its spectacular fifth and final season, Boston Legal tackles some of today's most inflammatory - and sometimes irreverent - social and moral issues, from teen pregnancy and the death penalty to sex surrogates and Alzheimer's. Now, as Crane, Poole & Schmidt faces financial ruin, its brilliant attorneys face chaotic caseloads filled with malpractice, murder, love and lust. There's a surprise engagement - or two - and, of course, the bittersweet final act of this remarkable series.

As in Munchkinland, people seem to come and go so quickly at the law firm of Crane, Poole & Schmidt. Out the door as Season Four begins are cast members Mark Valley, Julie Bowen, Rene Auberjonois, and Constance Zimmer (a tough loss). But the more things change the more they stay the same. Introduced to sweet, pretty and capable new lawyer Katie Lloyd (Tara Summers), it takes Alan Shore (James Spader) all of one second to come on to her. It takes Denny Crane (William Shatner) five.

In year 3, Boston Legal continues to toggle with ease between comedy and pathos. The season begins on a bittersweet note as Denise (Julie Bowen) gets engaged to the terminally ill Daniel (Michael J. Fox), who disappears to try an experimental treatment. Enter two new litigators, smart-talking associate Claire Sims (Constance Zimmer) and cocky partner Jeffrey Coho (Craig Bierko). Once Daniel exits the picture, Jeffrey and Brad (Mark Valley) compete for Denise's affections.

The classic combination of James Spader and William Shatner is just one of many reasons to savor the inaugural 17-episode season of Boston Legal. Making its highly rated ABC debut on October 3, 2004, this darkly comedic spinoff from The Practice looked like a formulaic reworking of creator David E. Kelley's previously successful series Ally McBeal, with similar plots and quirky characters enmeshed in personal and professional affairs of the heart at the prestigious Boston law firm of Crane, Poole & Schmidt.

Impressive in quality and quantity, the 27 episodes of Boston Legal's second season (2005-06) are a dazzling showcase for one of TV's greatest ensembles.
