A must-watch for fans of the trilogy. Skip it if you haven’t seen the first two. Watch it for Andy Lau’s career-best performance.
Rating: ★★★½ (Solid/Very Good)
Infernal Affairs III is not a crowd-pleaser. It is a requiem. It abandons the sleek thriller mechanics of the original for a slow, dreamlike, and deeply sad meditation on identity and punishment. The ending—which re-contextualizes the entire trilogy’s famous final line from the first film (“I’m a cop”)—is a gut-punch of existential horror. Infernal Affairs III
The non-linear editing is ambitious. The film jumps between three time periods without hand-holding. For attentive viewers, this reveals clever parallels and tragic ironies. For casual viewers, it can feel frustratingly opaque. The film assumes you have the first two movies memorized. It rewards rewatching but punishes distraction. A must-watch for fans of the trilogy
The biggest flaw, however, is the underutilization of the supporting cast. Anthony Wong’s SP Wong appears only in flashbacks, and while his scenes are poignant, they lack the weight of his presence in the first two films. Kelly Chen’s character is reduced to a near-cameo. and if you appreciate ambitious
The Infernal Affairs trilogy occupies a rare space in cinema. The first film is a masterpiece of cat-and-mouse tension. The second is a Shakespearean prequel tragedy. The third... is a psychotropic puzzle box. Infernal Affairs III does not give fans the simple, cathartic victory lap they might have expected. Instead, writers Alan Mak and Felix Chong, who also directs, deliver a dense, non-linear character study that prioritizes psychological disintegration over plot propulsion.
If you want more of the first film’s brilliant cat-and-mouse game, you’ll be disappointed. But if you want to see a masterful actor (Andy Lau) chart a man’s complete psychological collapse, and if you appreciate ambitious, if messy, storytelling, this is a solid and essential conclusion. It’s the Godfather Part III of the trilogy: flawed, overstuffed, and occasionally baffling, but unforgettable in its final, haunting moments.
