Community is useful for English practice if you can already follow natural conversations. At an intermediate level, the main story should be easy enough to follow. 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. 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 B2/C1, this can be a practical choice for practising everyday conversation and informal expressions.
