After Dark: On the Town: London Seen; April, 1975; Michael T. Leech;
...The second and third plays of the John Osborne season at Greenwich were disappointing, particularly The Picture of Dorian Gray, in which the playwright tries to emulate Wilde and succeeds not at all.
Michael Kitchen does his best and it has been suggested that he is miscast as Dorian. Perhaps the truth is that the part is unplayable and, as someone has already observed, if there was a play there, Wilde would have written it. Osborne's version rings with unfortunate lines. Can you wonder that an audience should titter when Dorian is made to declaim sonorously after the suicide of Sibyl Vane, "Now there is nothing to keep me straight"?
