Saw a wonderful documentary on PBS, titled the Lion in the House, about children dealing with cancer. See a review here and here in The New York Times. Death, tear-inducing pain and agonizing treatment dilemmas are all confronted head-on in "A Lion in the House," which will be broadcast over four hours Wednesday and Thursday on 1. PBS's series "Independent Lens." But the heart of the film is the vibrant, vital spirit of children. There's bubbly Alex Lougheed, 7, voted "cutest personality" at camp; easygoing Justin Ashcraft, 19, who has had leukemia for 10 years; and Tim Woods, who is fatherless and admits that he loves the extra attention he receives having cancer. The film's second half features an aspiring rapper, Al Fields, 11, and the determined, active Jen Moone, 6. A diverse demographic mix of age, sex, race and income, they were selected from several dozen children being treated at Cincinnati Children's Hospital Medical Center. Th
