Watchmen is a strong option for learners who already feel comfortable with English and want a more demanding challenge. Lines are generally delivered at a comfortable pace for regular listening practice. Learners will hear plenty of useful natural English, but some lines may still require a second listen. The complexity of the plot makes listening more challenging because learners also need to keep track of what is happening. Watchmen works best for learners around B2/C1 who are ready for a more complex story.
