Your watchlist
Save films for later, then rate them once you have watched.
Press Watchlist on anything in For You, Calibrate or a film's page to save it for later. Adding a film also tells the engine you're interested in it.
Once you've watched something, rate it from your Watchlist. That moves it off the list and teaches the engine whether it was a good call. Changed your mind? Remove it.

Your watchlist is my favourite feedback loop. Watch it, rate it, and I'll find you the next one.
