Ground Floor may not be the most original concept, but the actors seem made for their characters. When watching the show I don’t think “Oh, there’s John C. McGinley playing Mansfield” and “Skylar Astin pretending to be Brody Moyer,” I wonder where the character ends and the actor behind it begins. John C. McGinley makes you forget he’s Dr. Cox because he owns Mansfield. As for Skylar Astin, it appears he pretty much plays himself with a new name, which he gets away with because he has only been in a few things.
If McGinley, Astin, and the rest of the cast weren’t so good at their roles, Ground Floor would be boring. In “The New Office,” an older employee is fired and the young ones stab each other in the back to impress Mansfield. Thankfully, Brody and Threepeat are quirky enough that the backstabbing is friendly and silly. For example, Threepeat discovers a cool new way to sit down that he calls “the Riker,” after Commander Riker from Star Trek: The Next Generation, but it backfires when it tries it in Mansfield’s office because the chair back was too large. All the kissing up to the boss doesn’t pay off, when no one gets the empty office. Mansfield decides to give it to his plant because it was the only thing in the room that didn’t annoy him.
