In his review of the episode for Entertainment Weekly, Ken Tucker commented, "In a very nice performance utterly unlike anything he does on Dexter, Harrington let his hair get all bed-heady and spoke in a mumble-mouth drawl as he set up his favorite sadistic game: He lays a gun on a table, and has someone count down from 10. At "1," you're invited to reach for the gun, but that's when Ice Pick earns his nickname: He pulls out an ice pick, stabs your hand to the table, picks up the gun, and shoots you".^[12] Next, Harrington featured in a small but pivotal role in Christopher Nolan's The Dark Knight Rises (2012),^[13] co-starred as Alan Shepard—the first American astronaut to travel to space—in the CBS miniseries The Astronaut Wives Club (2015), and appeared as Jack, a lecherous photographer, in Nicolas Winding Refn's critically divisive arthouse thriller, The Neon Demon (2016).^[14]
