It's decent, all in all. For every powerful or exciting moment there are an equal amount of duds and predictable ones. Quite long, which helps convey the desperation of the prisoners but doesn't make for constantly gripping content. My recent interest in the Civil War helped raise my score a bit.

Great movie about the horrible times in a particularly cruel southern prison camp during the Civil War. Surprisingly good acting by some not-very-well-known actors.
