The episode received a rating of 43% with an average score of 6.2 out of 10 on the review aggregator Rotten Tomatoes, with the site's consensus stating: "While we've been waiting to spend time in Gotham's Arkham Asylum, 'Rogue's Gallery' was cluttered, confused, and borderline boring.
"[4] Matt Fowler of IGN gave the episode a "good" 7.2 out of 10 and wrote in his verdict, "I could have actually stood for more Arkham this week rather than paying obligatory visits to so many of the other Gothamites.
We see Selina Kyle peering out into the rain, also pondering, and Barbara sleeping next to Montoya, bottles of pills strewn about the nightstand.
It's jarring to go from a comical stage play to an investigation into amateur shock therapy, followed shortly by an exploration of deeply-felt insecurity in romantic relationships.
