“Fitzcarraldo” is not a perfect movie, and it never comes together into a unified statement. It is meandering, and it is slow and formless at times. Perhaps the conception was just too large for Herzog to shape. The movie does not approach perfection as “Aguirre” did. But as a document of a quest and a dream, and as the record of man’s audacity and foolish, visionary heroism, there has never been another movie like it.
