Fleabag can help advanced learners become more confident with fast and natural English. The narrative adds extra difficulty because learners need to track events, motives, or character relationships. 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, the British accent can make some lines harder to catch. With the dialogue moving at a natural rhythm, viewers should catch most of it, although a few moments may still be challenging. A learner around B2/C1 should be able to follow it, although the British accent may take some time to get used to.
