Snowpiercer 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. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 80 words per minute. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
