Heat
Very exciting movie, a bit on the long side, but to give all the characters a proper story/psychology I do think that it's a necessity. Peak cast, Al Pacino really stood out to me in this film. Robert De Niro also owned his character, which made it really entertaining to watch. Normaly I think gun fights are lame, but I have to say that the ending really had me on the edge of my seat, despite it being a gun fight.
