Bennett's lack of a theatrical grounding showed in the uneven construction of some of his plays. A successful first act followed by much weaker second and third acts was noted in his 1911 comedy "The Honeymoon", which played for 125 performances from October 1911. The highly successful "Milestones" was seen as impeccably constructed, but the credit for that was given to his craftsmanlike collaborator, Edward Knoblauch (Bennett being credited with the inventive flair of the piece). By far his most successful solo effort in the theatre was "The Great Adventure", based on his 1908 novel "Buried Alive", which ran in the West End for 674 performances, from March 1913 to November 1914. Sutton praised its "new strain of impish and sardonic fantasy" and rated it a much finer play than "Milestones".
