“Significant Other” begins as a gay “40-Year-Old Virgin” and ends up a gay “Bridesmaids.” That’s not necessarily a negative thing to say about Joshua Harmon’s new comedy, which opened Thursday at Broadway’s Booth Theatre. The show never feels derivative, even though you might get the impression you’ve seen this distraught hero before through a different prism in an alternate universe.
Jordan Berman (the remarkable Gideon Glick) is not 40 when we first meet him at a bachelorette party for one of his three close female friends. But no doubt about it: He’s definitely the eunuch in the harem. Not yet 30, Jordan probably isn’t a virgin, so he lacks the immediate tragic aura of Steve Carell’s character in “The 40-Year-Old Virgin.”
