South Park is useful for English practice if you can already follow natural conversations. The dialogue moves at around 167 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. If your English is near B1/B2, this can be useful practice, especially if you start with English subtitles.
