The show, which premieres on HBO Max alongside the whole channel’s launch on May 27, will feature real, human, celebrity guests like the Jonas Brothers, John Mulaney, and Jason Sudeikis, but also the regular cast of characters like Oscar the Grouch and the Cookie Monster. The show looks like a blend between adult interests — Kacey Musgraves will be one of the guests — and the vested interests of children, largely meaning puppets on Sesame Street. To many parents, the encroachment of Elmo into the any-time-after-the-sun-goes-down territory is, well, not as welcome as one might think. But the news is probably great for the world’s children, who want nothing more than more television and, quite frankly, more Sesame Street.
