Requiem for a Dream is a good choice for confident learners looking for more realistic and demanding listening practice. Lines are generally delivered at a comfortable pace for regular listening practice. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. Also, crime scenes may bring in words related to investigations, police or legal vocabulary. The narrative adds extra difficulty because learners need to track events, motives, or character relationships. It should work best near B1/B2, especially for learners prepared to handle a more complex story.
