In a retrospective review, AllMusic's Mark Deming hailed "Fun House" as "the ideal document of the Stooges at their raw, sweaty, howling peak", and wrote that it features better songs than their debut, significant improvement from each member, and Don Gallucci's energetic and immediate production. Dalton Ross of "Entertainment Weekly" wrote that the "radical" album sounded "primal, unpredictable, dangerous". "Pitchfork" critic Joe Tangari felt that the music's aggression has rarely been matched. He recommended it to "any rock fan with a sense of history" and asserted that, along with the Stooges' debut, "Fun House" is one of the most important predecessors to the punk rock movement. Barney Hoskyns called it a "proto-punk classic".
