Perfection of course belongs to God alone. That being understood, here are three films that come close:
The Passion of the Christ (2004)
Miracle on 34th Street (1947)
On the Waterfront (1954)
This was a tough one because there are a lot of very great films that I cherish, a true embarrassment of riches. Put your choices in the comboxes.
A Man for all Seasons
Gladiator
Back to the Future
