Are you effin kiddin me? BEL is a freaking PG-13 action movie that you take the family to go see. Nothing is very realistc, and the plot kinda sucks.
And on the other hand, you have a rated-R action flick that has gotten great reviews, has 100 Rangers/Delta Force Soldiers fighting in a city full of armed people, that is extremely realistic, and isn't made for Mr & Mrs Smith and the friggin kids.
BHD, hands down.
