What most reviewers, except Roger Ebert, missed by a country mile.
From 18 on (you can get drafted at this age, and drink legally in New York), young adults should not be patronised, or given mis-information. Case in point: Cole Porter's life, as depicted in "DeLovely." The critics I've read on this site didn't "get" the real Porter -- what motivated and influenced his songs, besides the amazing wit. His relationships with men and women were a mystery. It was a conflict that lay at the core of many of his songs. You don't put all that to one side, while you wait for the movie to get back on track with those great production numbers. The paradox of love was an intrinsic part of Cole's life, and influenced many of his lyrics. Read Roger Ebert ye critics.
