Tokyo Vice is a strong option for learners who already feel comfortable with English and want a more demanding challenge. 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. At an intermediate level, the main story should be easy enough to follow. If your English is close to B1/B2, Tokyo Vice can be useful for building confidence with more complex narratives.
