Too unrealistic
Who builds a house and lines the walls with dead bodies? There are better ways to get rid of dead bodies than decorating a house with them. Also 40bodies only wrapped at the head and nobody smells a thing until the drywall is exposed? bullspit
After the extraction 50 yards after crossing the US border 3 cars full of gangsters are carrying automatic weapons. bullspit
Why have 2 uncooperative local agents there just to provide cover for a CIA operation? I'm sure they could have easily found corrupt cops to look the other way.
I get what they were trying to do tho, and the movie accomplished it pretty well in the end.
