BoJack Horseman is a strong option for learners who already feel comfortable with English and want a more demanding challenge. The dialogue moves at around 165 words per minute, with frequent back-and-forth exchanges. Learners will hear plenty of useful natural English, but some lines may still require a second listen. Also, animated scenes often make the context easier to follow through visual clues. At an intermediate level, the main story should be easy enough to follow. For learners around B1/B2, English subtitles can make the first watch more manageable.
