The Zen Diaries of Garry Shandling is Apatow's "best, most focused" work since Freaks and Geeks, says Matt Zoller Seitz. Yet Seitz wonders if a documentary running two nights and more than four hours is excessive. "Is there too much of a good thing here? Maybe," he says. "There are emperors, generals, and Nobel-prizewinner scientists who don’t get four-and-a-half hours on HBO, and it’s possible that we didn’t need a detailed segment about Shandling’s voice-over work on the 2006 animated film Over the Hedge (even though it ends up being a testament to his work ethic; he extensively rewrote his own dialogue and took the role of a turtle very seriously). Although Shandling completists will love the segment on the digressive, quasi-documentary DVD supplements he created for the Larry Sanders Show box set, others may wonder if it wouldn’t just be better to tell people how they can order them...Still, anybody who was inspired and moved by Shandling’s work won’t complain about being able to luxuriate in this exhaustive account. Even the slack portions are intriguing because of the access Apatow has to the records of Shandling’s time on Earth."
