    Unfolds as a masterful chess match of wit and ingenuity, a cat-and-mouse chase of the highest order.
  2. Dazzling psychological cat-and-mouse drama.
  3. 88
    Throbs with action, suspense and a seductive rhythm all its own.
  4. It's hard to breathe in Andrew Lau and Alan Mak's Infernal Affairs, a relentlessly taut Hong Kong cop thriller that, unlike many of its cinematic peers, doesn't burn off tension in choreographed action sequences.
  5. The plot is intricate and tight. The preamble is a bit challenging to sort out. But the movie's engine is the relationships and the characters' inner lives, all of it boiling with emotional intensity.

  1. A artistically bizarre, action packed movie that has the untouchable tension between its characters. In my opinion, "Internal Affairs" is better than the American version of the movie, "The Departed". Full Review »

    I liked this one better. People don't realize that the Departed is a remake of the Infernal Affairs trilogy. The Departed does take sources from IA 2 and 3. To say that this movie is a rough draft of Departed is downright insulting. WIthout this movie, there goes the Departed as well as Scorsese's career. This movie is much better. The characters are more interesting and this film has more soul than the American counterpart. A much better thriller overall. Full Review »
  3. The film that got Scorsese his first Oscar is a remake of this wonderful film, a very perplex and masterfully weaved chess match of wit and ingenuity. The scenario deserves all possible accolades and the directing is very sharp indeed. Full Review »
