His death stare..And the scene where Batman hands over his body down to Lois Lane..and her receiving it and kissing that beautiful mass of a hunk in her arms..FUCKING HELL! Slow motion is a must for me.
Or perhaps you like Brandon Routh better? He gets beat up by Lex's lackeys and then gets stabbed by a Kryptonite crystal which is then broken off and embedded in him. Left to drown at the bottom of the cliff.
There's just something about how he is picked up from behind with his head resting against Lex's chest, dripping wet in his tight suit, totally weakened and then stabbed. Imagine the moment he gets stabbed and you feel his body jerking with pain and his breathing quickens and you feel his chest and body heaving up and down in panic. Then you savour the moment a little longer and let him fall back to the ground.
