An effective film if you love the series and the characters; an OK one if you have seen the first two films and a pointless one if you haven't seen anything, 18 December 2006
Author: bob the moo from United Kingdom

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.
