Ozark is a strong option for learners who already feel comfortable with English and want a more demanding challenge. 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. With the dialogue moving at a natural rhythm, viewers should catch most of it, although a few moments may still be challenging. At an intermediate level, the main story should be easy enough to follow. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
