broadening the discussion a bit:

there is an alternative scene near the ending of Michael Mann's Manhunter which I always thought realliy made it a much more profound film.

Right after will graham has stopped the serial killer he goes to visit the family slated to be the next victims - but the scene is ambiguous about whether graham wants to see who he saved, or if he still has the 'killers thoughts' running around in his head. its dark and a bit tense and makes a great counterpoint to the bright sunny beach final scene.
