Gilmore Girls can be good for learning English if you already understand everyday conversations and want more consistent practice. At an average of around 121 words per minute, the dialogue is generally manageable, though some exchanges require more attention. 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. Because the plot is fairly straightforward, learners can focus more on the dialogue than on figuring out the story. If your English is close to B1/B2, Gilmore Girls can be useful for getting used to faster spoken English.
