Mad Men can help advanced learners become more confident with fast and natural English. Learners will hear plenty of useful natural English, but some lines may still require a second listen. Following the story requires attention, so language difficulty is not the only challenge here. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 117 words per minute. If your English is close to B2/C1, Mad Men can be useful for building confidence with more complex narratives.
