Joker: Folie à Deux is a strong option for learners who already feel comfortable with English and want a more demanding challenge. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. The storyline is easy to follow, so missing a few words should not stop learners from understanding what is happening. At an average of around 89 words per minute, the dialogue is generally manageable, though some exchanges require more attention. For learners around B1/B2, this can be a practical choice for building listening confidence.
