Person of Interest: The pilot was amazing in every way but the greatest scene is the one where the two main characters meet for the first time, under the Brooklyn bridge by the river. It's beautifully shot, very mysterious (makes you wonder 'who the hell is this guy and how does he know everything?') and sets the mood for the entire show. Also, it has memorable quotes.

'You don't know anything about me.'
'I know exactly everything about you, Mr Reese.'
