Babylon 5 can help advanced learners become more confident with fast and natural English. The complexity of the plot makes listening more challenging because learners also need to keep track of what is happening. Learners will hear plenty of useful natural English, but some lines may still require a second listen. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 107 words per minute. If your English is close to C1/C2, Babylon 5 can be useful for building confidence with more complex narratives.
