How bad is it? Propaganda poised as thriller. Doesn't work.
Should you see it? No.
This film starts with the premise that the religious right are persecuted in America. Now, if you assume that that's an alternate reality just for a movie and not the truth in real life, it's possible to review the film on its merits rather than on the politics of its makers. It still sucks. A senator proposes sweeping religious reforms and wants an evangelist to support him. When that evangelist doesn't, he gets framed for murder and then has to go underground to fight a corrupt government and people trying to undermine his faith. Dean Stockwell and Fred Thompson aren't the main actors, but the most recognizable. Fox anchor Gretchen Carlson essentially plays herself. It's uninteresting as a thriller, leaving its message as the only reason it exists - it won't convert anyone.
