As a 20 year Military veteran, I was attracted to the intriguing question that is the title of this movie. Deciding whether or not to watch it becomes a no-brainer when you see the list of names that make up the ensemble of the cast: Ernie Borgnine, Ivan Dixon, Don Ameche, Art O'Connell and the great John Fiedler are all solid actors and have appeared in some of the best films in the history of American cinema. (check out their collective credits if you doubt it.)
This film is an underrated one in the canon of films dealing with the U. S. Military. The script, although not perfect, is well written, with subtle and witty commentary on the military hierarchy, prevailing social attitudes, and the precarious relationship between our Vietnam-era military and the civilian community (i.e. "community relations"). No heavy military rigidness here; the flow is free and easy as in 'Catch-22' to provide a frame of reference. Or, as Stephen Sondheim wrote around the same period in "Anyone Can Whistle," the 'laugh at the Kings, or they'll make you cry' approach.
As would be expected, Brian Keith is solid, but surprisingly even Tony Curtis manages to turn in a relatively piped-down performance from his usual fare which, to quote America's best known homemaker Martha Stewart, 'is a good thing.'
