Caramelo can be good for learning English if you already understand everyday conversations and want more consistent practice. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. Also, jokes, quick reactions and casual exchanges are a regular part of the dialogue. At around 68 words per minute, the rhythm of the dialogue is manageable and easy to follow. The story gives enough context to follow what is happening easily. Caramelo works best for learners around B1/B2 who are ready for more demanding vocabulary.
