School of Rock can be good for learning English if you already understand everyday conversations and want more consistent practice. The story gives enough context to follow what is happening easily. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. Also, jokes, quick reactions and casual exchanges are a regular part of the dialogue. With the dialogue moving at a natural rhythm, viewers should catch most of it, although a few moments may still be challenging. For learners around B1/B2, this can be a practical choice for getting used to faster spoken English.
