What makes it different from others?

Boring, over-political, tech fuzed mess

It's an amazing and heartbreaking story.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.

Where Scorsese's recent version of Infernal Affairs all the loose ends pretty much got tied up during the film whereas with the original we were left with an open (but much more emotionally impacting) conclusion. The first sequel was a prequel so part III was left to pick up afterwards while also going back over the original film and filling in more detail. In doing this it marks itself out as one that is aimed at the fans rather than being just out for money. The downside of this is of course that if you are not a fan you might find this hard to follow along with (and if you have not seen the first film then just forget it totally). Personally I thought the first film was an enjoyable cop thriller but I didn't think it was brilliant or developed characters that well but the tension was great. With the third film the focus was very much on the characters rather than the tension – with the fate of Ming being the modern thread that holds the film together.If you are into the characters and the parallels with the original film then it is worth seeing because it does do it pretty well. It does ask you to pay attention but it rewards you if you do and have been. There is action but mostly it is the Ming's ongoing struggle with who he is that the film pays most attention to. I quite liked this but must confess that this film still didn't do a great job of bringing out the characters that well and it is more the events and revelations that kept me interested rather than an emotional buy-in with the characters. Lau is perhaps partly to blame for this because I thought he was buttoned a bit too tight – it was understandable in some regards but the third film should have been the point where he shows more of a breakdown (which he does, but again it is events rather than emotion). Leung is good again but his scenes don't seem as relevant or as interesting within this film – again it is probably to do with the lack of emotional buy-in I felt with his character; his performance is natural and engaging though. Outside of these two the rest of the cast are pretty good. Again I didn't think much of the use of Chen but Wong and Tsang are both solid in their small returns.Overall then an effective and enjoyable film if you love the series and the characters; an interesting one if you have seen the first two films and a pointless one if you are looking to join in at the last minute. Tying up the loose ends of the series, the film isn't tense enough or emotionally impacting enough to be worth a look unless you are really already into the characters but it is an interesting way to bring things to an end – with restraint and tragedy rather than excess.

If you loved the first two 'Internal Affairs' movie, then you'll probably find it easy to also enjoy this concluding part: if not, you may find it more difficult. Part one was a tense thriller; part two, more epic in tone, a prequel that filled in the back story, concentrating on some of the secondary characters from the first film. But it's not completely clear where there's any plot left to fill a third part. What this film does is overlay the previous stories with an additional layer of romanticism and complexity; but there's a certain lack of focus to the plot, with almost all of our favourite characters already dead by the end of the second film (although, in flashback, there's a rebirth for the great Tony Leung, absent from part two). Indeed, the film works almost entirely by encouraging us to feel differently about scenes we have already witnessed. I still liked this third story about the quiet men of violence, and it did succeed in feeling like something more than just a repeat of the earlier films. But it's not so clear how much it adds to them.

What exactly is her intention when dealing with Ming? Nick_Vorobyov said that she was contacted by Shen and was trying to test if Ming is a spy.But that doesn't make a lot of sense.Especially when she received the tape from Yan. and she called Ming without even listening to it.If she does not trust Ming, why doesn't she at least see what the tape is about?Also, she seemed more or less shocked when Ming confessed to her "I don't want to be Sam's guy anymore."So when she showed Yan's profile to Ming(or did she do it unintentionally?) on her computer and later hinted him the password, what exactly was she trying to do?

Infernal Affairs 3 builds cleverly on the plotline of the first movie, but with its complex story and frequent switches between past and present, is likely to seriously confuse anyone who comes to it without having seen Part 1 first to understand the two main characters. For those who have, this film brings out further details of the relationship between the two, superbly played again by Tony Leung and Andy Lau. With frequent flashbacks, the film focuses on extending the story of Triad mole Ming (Andy Lau), warping up the tension as the stresses of his double life become intolerable. Leon Lai's usual expressionless performance, which mars his other films, works well here as it leaves you few clues about his character's motivation until the climax.If you enjoyed Part 1, you will enjoy this. (I haven't seen Part 2 yet.)
