He concluded, ""Imaginary Friends" has the feel of a work by a new playwright who was recently quoted as saying that she 'got a taste of the freedom that theater offered . . .' What the playwright failed to recognize is that the theatre has its own rules; e.g., thematic and stylistic consistency." In his review of the Broadway production, Ben Brantley of "The New York Times" said it "isn't a show that leaves you gasping at its daring or chuckling over its cleverness. In chronicling a feud between two politically engaged, exceptionally feisty women within a literary world of men, Ms. Ephron makes her points dutifully, clearly and repetitively . . . In trying to appeal to both those who are and those who are not familiar with the play's high-brow heroines, the show winds up sacrificing its dramatic energy to Cliff Notes-like expositions disguised in masquerade costumes . . . Hamlisch's songs, with lyrics by Craig Carnelia, are tuneful, jinglelike numbers that add little in period flavor or character definition. And some of them simply slow things down to no purpose." Reviewing for "Talkin' Broadway", Matthew Murray noted Nora Ephron "has a thrillingly theatrical concept that she simply hasn't taken to its furthest extremes. This being her first play, that is perhaps understandable, and "Imaginary Friends" is never incompetent or boring. It does manage to be exciting occasionally, but less often than it should be . . . What Ephron gets right is her depiction of Lillian Hellman and Mary McCarthy as avatars for the diametrically opposed (maybe) deities of 'fiction' and 'fact.' . . . When "Imaginary Friends" tackles that aspect of the story, presenting its scenes with the flair and creativity only theatre can allow, the play is at its best . . . These moments . . . are theatrically astute and emotionally honest . . . Scenes that give us greater insight into the characters are always the most successful and entertaining." He called the songs "the most puzzling component" of the play, commenting, "While the songs don't slow down or detract from the action, they do not particularly enhance it." He concluded, "What is missing, and would probably have made the show more effective, is the literary music created by McCarthy and Hellman. For the most part, their writings - as lyrical and incisive as one is apt to find - are missing from the play, and the contributions of Hamlisch and Carnelia are a poor substitute.
