Feel the heart of the Chef
29 December 2003 | by (Hong Kong) – See all my reviews

I've watched Infernal Affairs I, II & III, in a year time. I loved the first one very much. It gave me a very unexpected feeling. It's simple but strong in impact. Though one could mention a lot of flaws in the plot, I just couldn't resist its charm. The second one made me disappointed because it lacked the kind of impact the first one gave me. Now after watching the third one, I realise why there needs to be a second one in totally different style than the first one. It's a preparation for the audiences adapting to the change in the third one.

I like this third one. Without the second one, probably I would have been like the other audiences critising the change of style from the first one. It's this kind of change, it's made the film more solid, full of human feeling. The first one indeed was touching only the surface of the hole. This third one is more into the content of it - the heart of the people.

I love particularly the part describing Andy Lau's psychological sufferings and changes. The shadowing effect he had with Tony Leung should deserve a credit for script writing, directing and editting. The interlacing of stories between that happened before and after Tony Leung's death has been editted great. I feel sorry for people who don't read this or who don't like it. It's certainly the best part of the film which should earn a credit rather than negative critics.

I would conclude that the first one is like spicy cuisine which is strong in taste and quick in making one like it immediately if you can stand it. The third one is somehow a French cuisine where you have to be patient, taste it slowly together with the wine before you appreciate the marvellous cooking skills and feel the heart of the Chef.
