David E. Kelly has been a wonderful, prolific writer/producer/creator of television shows that have made me laugh, think and cringe since he joined the writing staff of LA Law. He rose in my estimation when he created Picket Fences, a show about an eccentric town but also a series about family. His characters were unique, they were flawed and when he trapped them in the same room and let the words fly, he wrote compelling theater.For those unfamiliar with this terrific show, the first season is just coming out on DVD this month. It’s certainly one I look forward to re-watching at some point.However, as brilliant and talented as David Kelly can be, he is also self-destructive and there appear to be no people who can govern him, trimming his excesses. The pattern has repeated itself time and again, from Picket to Ally McBeal to Boston Legal.It’s more glaring today in the absence of the meaty subject matter we had to chew over from Aaron Sorkin’s West Wing. There, Sorkin sought out dry and seemingly boring topics and then had his characters hold forth in riveting ways. His characters were passionate and took sides and shifted allegiances and were fascinating.Today, the only show that seemingly touches on any of these moral and ethical issues ripped from the headlines can arguably be Boston Legal. Every time Alan Shore stands up, complete with soap box these days, he makes a wonderful speech. Shirley Schmidt, in court anyway, also makes impassioned speeches about important topics. The court cases are what make the show compelling to watch week in and week out.It’s away from the court room that has soured Deb and even Robbie on the series and can make me wince on more than one occasion. The eccentricities of David Kelly’s characters make them special and he always has a great eye for casting. But, after a while, Kelly forgets character and sticks only with their foibles and tics turning his people into caricatures. As seasons pass, he begins to populate his shows with characters that stagger the imagination and strain the reality of each series. Ally McBeal, for example, really headed south about the time Dame Edna became a regular and I see it happening again with the addition of Clarence/Clarice as legal secretary to Claire on Legal.Kelly seems not to know what to do with his sprawling ensemble and has them engage in sophomoric behavior, none more infuriating than this season’s sexual escapades of Denise, Brad and Jeffrey. He’s also suddenly sent out an interesting message that Denise engaging in a round of casual sexual suddenly gets pregnant — I guess adults using common sense protection wouldn’t occur to these brilliant lawyers.Anyway, Kelly’s messages about Katrina, anti-Semitism, the pharmaceutical business, Homeland Security and the rest get overshadowed by the over-the-top antics that surround the series. It feels schizophrenic and while I will stick with it because of those issues, I feel the show has begun to lose its way in typical David Kelly style.
