The Departed
Why was this so good? I mean this movie is so creative at the cat and mouse or maybe rat and mouse. That it keeps you intrigued for the whole run time. Watching Sullivan climb up the ladder of the Bahstan police department is amazing also the irony of between Billy and Sullivan's interviews is amazing because the clean-cut all american boy scout has some dirt underneath his uniform while the dirty and muddy police academy failure is the actual guy they think sullivan is.
The 3rd act is also amazing I'm debating on where dicaprio was better this or The Aviator because he is fantastic in both also the blocking and shots especially when Billy figures out Sullivan and walks right behind his back similar to how Sullivan did to the police department is flawless.
