An American Hack of Mou Gan Dou (Infernal Affairs) and its a winner of 4 Oscars.

Rating: 6/10 (5 July 2009)

I shouldn't discredit this movie too much, I still think The Departed is still a good movie. I recently watched Mou Gan Dou prior to this and it still fresh in my memory. I predicted how it was going to end and who was going to die.
Shame on us Americans for stealing other imported ideas, like Ringu, Rec, La Femme Nikita, Let the Right One In, and now this. I am sure the originators in China are getting credit of crafting such an incredible story line and the producers and the writers of The Departed have done their best to warp the script and implement new intriguing characters the best way possible. But everything else is an obvious carbon copy of Mou Gan Dou.
It was well acted, produced and directed. I can't possibly give it a higher score because I saw the derivative of this movie first. If I saw this movie first, I would have liked it more and I probably wouldn't have noticed the Chinese Predecessor.
Overall, I will still recommend it. The entire cast is enjoyable to watch even though it gets pretty shallow in the end, just like the original.
