I never thought I'd say this but DiCaprio is perfect in this.

Rating: 9/10 (16 October 2006)

I've just watched the Departed and I'm a big big fan of Infernal Affairs.
I must say, I enjoyed The Departed immensely. It was smart, very funny in places and the performances of DiCaprio, Wahlberg and Winston were fantastic.
I really didn't think Leo would be able to make me empathise with his undercover cop character the way Tony Leung did. But I must say, I was wrong, this is the film where DiCaprio comes of age as a fine actor. He deserves and Oscar nomination for this in my opinion, no question. There is very little between Leo and Leung in terms of performance (I perhaps lean slightly toward Leung as he is the finest Asian actor of the modern age I believe).
All in all, a great but flawed film (some additions to the plot worked, some did not) and a return to form from Scorsese
