Roger Ebert writes very well about a few classic movies -- not only that, he keeps revisiting them over time, and writing more about them as the situation dictates. La Dolce Vita is one of those films. It helps that I love the movie, too, but, it's clear Ebert responds to Fellini's film on a profound personal level:
Although it is great, I have seen greater films than "La Dolce Vita." But it is the film of my life. By its eternity I measure my time.
