12 Angry Men
The best thing about old movies that you aren't interrupted by cgi or wild camera effects but you're 100% focused on the plot and the characters and the camera angles actually meant something back then as you see the camera zooms in more and more as the time passes and they start getting more focused on the case not the outer factor that's occupied their minds before they got here and the dialogue I can swear I have never witnessed anything like that before and actors close up scenes when they actually realize something new about the case and the display of shock on the one who agree and the display of denial on the one who didn't agree was spot on and then the climax when they realized the truth and the denial of the second judge who couldn't forgive his own son was acted magnificently and when they left the racist one talk and everyone turned away that put a smile on my face.
Every actor played his role so well but fuck I wished someone just punch the old racist motherfucker and knock him out (not because he was racist but he was so fucken annoying).
