How to track the movies and shows you watch
Most watch lists die the same way: they ask for too much. This is the smallest routine that still answers "have I seen this" and "where did I leave off" a year from now.
Keep one list, not three
A film on Friday and a series you are three seasons into are the same question — what have I watched — so they belong in the same list. Splitting them across apps is how half the answer goes missing, and it is why most people cannot say what they watched last year.
Record two things and nothing else
What you finished, and where you are in what you have not. A rating is worth adding while the credits are still running; a written review is worth adding only if you want to write one. Anything a tracker demands every single time is something you will stop doing by March.
Mark episodes as you go, not in batches
Ticking an episode takes a second at the end of it and five minutes a month later, when you are counting back through a season trying to remember. Progress recorded late is progress recorded wrong.
Let the list decide what is next
The point of the whole exercise is the evening you cannot choose. A list with statuses answers it: what is half-finished, what aired this week, what you added and forgot. That is worth more than any recommendation engine.
