The element that you can’t help but respect in Bright Lights: Starring Carrie Fisher and Debbie Reynolds (HBO, 1.7) is the honesty with which it regards the humiliations of aging and creeping illness as suffered by Debbie. She’s a trooper and a toughie, you bet, but the hill keeps getting steeper and thornier, and your heart goes out. Thank God for the fine comic relief of Carrie’s perspective, which includes relentless servings of candor.
