I thought it was mildly entertaining. Probably won't watch it again, but I felt as if I got my money's worth.
On the other hand, I was repulsed by the major ANTI-AMERICA mood that the movie presented. Maybe I'm just paranoid of Hollywood, but it seemed a little too preachy and full of 'America is evil' propaganda for my tastes.
One could argue about the historical accuracy of the events, however, the whole evil villain w/ the US flag draped over his shoulders and Bald Eagle fake eye REALLY stank of propaganda too me. They tried to make the character look so evil, but at the same time so patriotic (in his own mind) that I couldn't help but feel that they view us (gunowners who love our country) in the exact same light.
But then again, maybe I'm just analyzing it too much...
