Better Call Saul is useful for English practice if you can already follow natural conversations. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. Some parts may require more focus, but the main story remains easy to follow. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 98 words per minute. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
