Watching alone leaves you with the entertainment. How to make it study.
Binge-watching a favourite show with subtitles is pleasant, but it does not move your ability much on its own. Your eyes are reading the subtitles while your ears rest. The fix is not to mix the two: watch once purely for enjoyment, and study a short segment separately.
Medical, legal and crime series carry heavy terminology that weighs on beginners. Sitcoms and family dramas built on everyday conversation are a better start. Shows with 20โ30 minute episodes suit repetition. Rewatching something whose plot you already know works well too.
Trying to study a whole episode exhausts you into quitting. Pick a five-minute stretch you liked: once without subtitles, once checking with them, once more without. Repeating the same stretch across several days lodges the expressions in it whole.
Writing out what you cannot catch shows exactly where you get stuck. It is slow, though, so there is no need to do it for everything. Using it on just one or two stubborn sentences already helps.
Expressions picked up from a drama stop at recognition unless you use them. Noting down lines you liked and working them into a monologue or a short diary entry converts them into language you can produce. Slang and a particular character's verbal tics may not transfer to real conversation, so it helps to mark those separately.
