American Dad! is useful for English practice if you can already follow natural conversations. The dialogue moves at around 144 words per minute, with frequent back-and-forth exchanges. Some scenes use denser language, so learners may need to pay close attention to word choice and phrasing. The story gives enough context to follow what is happening easily. If your English is close to B1/B2, American Dad! can be useful for getting used to faster spoken English.
