Abrupt endings... (Spoilers)
The Babylonian Story ended with the fall of Babylon and the deaths of all Babylonian characters. Prior to the scene, it was mentioned that Babylon and the cuneiform disappeared from the earth, but no depiction was made as to what Cyrus' rule meant for the inhabitants of Babylon.
The Judean Story was only referenced when a parallel needed to be made between the Passion and one of the other stories. It received no true ending, but our last view was of Christ being crucified; no doubt meant to depict Christ as a victim of intolerance. Jesus was met with intolerance, but that is not where the story ended and Jesus was not defeated. Griffith portrayed Christ according to the Bible which states that Jesus was not defeated, but rather allowed himself to be crucified and then rose again.
The French Story had scarcely gotten off the ground to begin with. The stage was set in the first act and the outcome came in the second half. Brown Eyes and Prosper Latour were killed during the St. Bartholemew's Day Massacre, yet there was little character development to create sympathy for the doomed couple.
The Modern Story ends with The Boy being pardoned, but the plot about the child being taken from the The Dear One was abandonned. In the second act, there was a flashback to the hospital where the baby was being neglected by the hired mother, but there was no other reference made after that. The husband and wife are together again and the story ends without any resolution to the child's story.
The epilogue scene was rather odd as well. Angels interrupted the fighting during a war (The World War? The American Civil War?) and a prison turned into a field of flowers.
