The original version is better

Rating: 1/10 (10 December 2006)

They sure know how to make their version real 'American' with all the F words. That seriously was annoying, how every actor in the movie always needed to curse, I should have counted them.
The original (Infernal Affairs/Mou gaan dou) is way better.
Why? Cause the most important key was missing! In the original movie; the mole (Chan Wing Yan (as Tony Leung)) in the mafia gang had a great bond with the head guy of the entire case. He gave him a watch for his birthday. At that moment you could see how those two has a bond with each other. That would explain the grief that he showed in the movie when the head guy got killed.
The American re-film: Billy and Queenan totally had NO connection in my eyes. All Dignam could do was bash him with the f words. Why the hell would Billy give a crap that Queenan died? They had no bond.
I think supposedly in both movies the death of the head guy was the twist in the cases. The both moles (mafia side aswel the police side) realized this cannot continue anymore. Afterwards they had to take strong measurements to the case. That all cause of the death of that head guy.
So yeah, I advice everybody to watch the original one first. I think this movie is too overrated. I sure hope they won't re-film part II and III of Infernal Affairs (it is possible you know...).
