Films that at first appear to go for realism

but then become more metaphorical.  I never noticed the symbolism in Platoon on first few viewings.  I watched it again the other night and it's filled with it, blatantly obvious but never detracting from the realism of the film.  In one scene a soldier is in a recently abandoned enemy camp and finds a box filled with plans.  He tried to take it and just as he does so he sets off a trap and both his arms are instantly blown off, and he stumbles for a few moments before dying almost instantly.  This idea is everywhere in the film, plans turn to chaos, the old image of the heroic soldier becomes a sort of powerless figure blindly stumbling between life and death.  Time and time again characters are rendered powerless and die, until there are no more lines and plans and it finally becomes a chaotic firestorm.  Apocalypse Now too goes for symbolism and metaphor, but seems less realistic, but then I wouldn't know, as I know nothing about Vietnam save a few things I've read.
