SERIES PREMIERE: What a great idea for a TV talk show. No audience, no desk, no couch – just a barber shop, where LeBron James, in this new show from HBO Sports, hosts a small group of invited guests, who hang around “the shop” and engage in some freewheeling, topical conversation. The guests for this opening edition hint at how wide-ranging James expects the guest list to be as well: The shop patrons for tonight’s opener include New York Giants wide receiver Odell Beckham Jr., Los Angeles Sparks WNBA basketball player Candace Parker, Golden State Warriors NBA player Draymond Green, Snoop Dogg… and Jon Stewart.
