Jonathan Steinberg and Dan Shotz know they're trying to meet high expectations with Percy Jackson and the Olympians. Having previously collaborated on shows like Jericho, Black Sails, and The Old Man, the duo now find themselves tasked with translating Rick Riordan's beloved middle-grade novel to television in a way that satisfies longtime fans and newcomers alike. This endeavor meant finding the right cast, adapting book scenes that never made it into the two films starring Logan Lerman, and nailing the look of the novels as readers around the world envisioned it in their heads. A task that, if early Percy Jackson reactions are any indicator, they pulled off quite effectively.
