Hot Fuzz is useful for English practice if you can already follow natural conversations. The storyline is easy to follow, so missing a few words should not stop learners from understanding what is happening. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. Also, crime scenes may bring in words related to investigations, police or legal vocabulary. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 101 words per minute. If your English is close to B1/B2, Hot Fuzz can be useful for building listening confidence.
