Forever is a strong option for learners who already feel comfortable with English and want a more demanding challenge. At an intermediate level, the main story should be easy enough to follow. 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 114 words per minute. For learners around B1/B2, this can be a practical choice for building vocabulary range.
