The movie wrestles with a profound moral quandary and viewers can decide what's right and wrong for themselves. War is depicted as ugly and brutal, but the Navy SEALs also show the considerable courage, strength, and dedication it takes to make the team, which makes them seem highly admirable. While some parents will find the patriotism, sacrifice, and heart the soldiers display incredibly moving, others might be concerned that war and the military appears in too positive a light, and might come off like a recruitment movie.
The relentless battle violence is brutally realistic, shocking, and horrific. The battle does not go as it might in a normal war movie. Characters are shot in every conceivable part of their bodies, sprain their ankles, fall from cliffs, lose their fingers, bash their heads, and pass out. The fight is chaotic and desperate, with a great deal of blood and many bloody wounds. A character digs bloody shrapnel out of his wounded leg. Many characters die. A helicopter explodes, killing a number of men inside.
We hear plenty of sexual innuendo ("pushing peter," etc.) among the men during the movie's first half, before the fighting starts.
Language is very strong and constant, including "f--k," "s--t," "c--k," "balls," "crap," "bitch," "hell," "shut up," "muff," etc.
