Chicago is useful for English practice if you can already follow natural conversations. At an intermediate level, the main story should be easy enough to follow. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. Also, jokes, quick reactions and casual exchanges are a regular part of the dialogue. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 108 words per minute. If your English is close to B2/C1, Chicago can be useful for practising everyday conversation and informal expressions.
