Slow pace in the most part of the movie.

An action-packed slog

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
