Friends 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. At an intermediate level, the main story should be easy enough to follow. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 94 words per minute. If your English is close to B1/B2, Friends can be useful for practising everyday conversation and informal expressions.
