Some critics also felt that the play was derivative of other works (particular the early plays of Harold Pinter and the work of Jean Cocteau) with "City Limits" critic Lyn Gardner writing that the script was “derivative of some (more famous) playwrights' worst plays”. In comparing the enigmatic quality of the play to the work of Pinter, Maureen Paton wrote “Where Pinter's ironic technique like a two-way mirror can give an intellectual patina to a mystery wrapped in an enigma, Ridley seems luridly self-indulgent… Ridley drops various ominous hints that are never resolved, leaving the audience to wallow in the mire of pointless speculation.”
