Saw it with my wife today. It wasn't cheesy as most made-for-Christians movies tend to be, and the production values were top-notch. But it's a straightforward tale of conversion that's simply not going to have the same kind of dramatic action movie pacing or thriller movie pacing that modern audiences expect. So you have to already be interested in the basis of the story to really enjoy the movie.
Jesus was very well-acted and the swarthy, not handsome actor was a good change. Bartholomew....umm, kinda hard to take--I expected him to throw in a "like" or "man" or "far out" sooner or later.
The first part of the movie runs much like a police procedural, and that's okay. It changes direction, though, which may bother some people.
I thought the Romans in general were well done, and I especially liked the example of realistic Roman infantry tactics at the start of the movie. I've been doing quite a bit of research on the Roman military during that period, and this movie was very good, not only on the technical details, but also how duty in Judea would have "degraded" some of those details. They would not have been as shiny and "squared away" as soldiers doing duty in Rome, and the way they were degraded was realistically depicted.
Spoilers below:
There were two things that annoyed me. One was the implication that Mary of Magdala had been a prostitute (popular misconception, scripturally untrue) and had been actively selling her body even to Roman soldiers right up to the time Jesus was crucified (again, not according to scripture).
The second was that Clavius would have been welcomed by the disciples even to almost becoming one of the Twelve, and would leave their company by his own volition. Scripturally, we know that Peter was extremely anti-Roman right until the conversion of Cornelius, and still moderately prejudiced against Gentiles for another thirty years. I would like to have seen Clavius trail the disciples from a distance (as he started) and then approach Jesus alone, as he did.
The ambiguity of the ending was honest. No guarantee of "happiness," but a promise of peace. What's important is that Clavius had never expected his life to be happy anyway--he had always only hoped for peace at the end of it. He actually did get that one thing he said he wanted, what he had said to Pilate that Jesus repeated to him, when he sent his former adjutant away. It's probably a subtle thing that ultimately, Clavius gave up nothing that made him happy.
