Training Day can help advanced learners become more confident with fast and natural English. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 101 words per minute. Learners will hear plenty of useful natural English, but some lines may still require a second listen. The narrative adds extra difficulty because learners need to track events, motives, or character relationships. If your English is close to B2/C1, Training Day can be useful for building confidence with more complex narratives.
