Watching plan
In TeakReader you can import the subtitles of any episode, see the words you don’t know yet, and study them as flashcards before you press play. How it works

We took English subtitles for 12 episodes spread across the first seasons (S1E1, S1E3, S1E6, S2E2, S2E5, S2E7, S2E10, S2E13, S3E3, S3E5, S3E8, S3E11), removed sound descriptions, speaker labels, and character names, and matched each of the 37,253 spoken words to the same frequency list we use for classic book levels. Speaking speed is spoken words divided by the time the subtitles are on screen. Only statistics and single words are shown here.
The recommended level is our estimate from vocabulary, speed, and style, not an official CEFR rating. Later seasons can be easier or harder.
