The Boss Baby is a useful option for intermediate learners who want natural English without jumping into something too difficult. The vocabulary is usually clear and direct, which makes the listening experience less intimidating for lower-level learners (more than 81% of the words come from common English vocabulary). At an average of around 77 words per minute, the dialogue is generally manageable, though some exchanges require more attention. The storyline is easy to follow, so missing a few words should not stop learners from understanding what is happening. If your English is close to A2/B1, The Boss Baby can be useful for getting used to faster spoken English.
