Succession is a good choice for confident learners looking for more realistic and demanding listening practice. At an intermediate level, the main story should be easy enough to follow. Learners will hear plenty of useful natural English, but some lines may still require a second listen. At an average of around 114 words per minute, the dialogue is generally manageable, though some exchanges require more attention. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
