Six is well done picture. I am glad to see that the movies that can be labeled "Christian" are improving. The plot line of six is mostly believable.
The actors do a good job with making you feel as though you are with them in their experiences.
The movie covers a time during the reign of the Anti-Christ. It does not attempt to cover more than just a narrow time.
There are a couple of things that are not really believable. The writing on the walls will not be something that is allowed during that time period. Bible Studies are definitely out.
This picture did leave me wondering until the last minute of the ultimate disposition of the main characters. That really enhanced the value of the movie. It does not beat you over the head with Christianity and allows you to see a different view and see what you think.
