Diane Sawyer’s April 24 interview with Caitlyn Jenner on ABC was not just a ratings hit with 20.7 million viewers, but a critical one too, with consensus that the two-hour news special had managed to handle with sensitivity a difficult subject. Now comes ‘I Am Cait,’ E!’s eight-part documentary series set to premiere July 26, about Jenner’s gender transition and its impact on the network’s linchpin ‘Keeping Up With the Kardashians’ clan. E!, not known for tonal delicacy in its handling of social issues on such staples as Shahs of Sunset and Botched, has brought on a trio of well-regarded transgender consultants – two Los Angeles-based therapists plus Jennifer Finney Boylan, the national co-chair of GLAAD’s board of directors – to keep the series, produced by Bunim/Murray, in line.
