Solid Hong Kong action-thriller with good performances and fine direction. I do think The Departed did better with connecting the plot and character development (particularly between the undercover cop and psychiatrist). Also thought The Departed was more suspenseful. But that said, Infernal Affairs ... is a fine film. **3.75/5**
