The last movie I watched was WarGames (1983), after seeing it mentioned on this board.
I suffer from PDS (Patience Deficiency Syndrome) and usually abandon movies, TV episodes, and documentaries around the 15 minute mark. I gave up on WarGames far later on, at the point where the kids meet Dr Falken. Later I went back and finished the movie, just to see more of Ally Sheedy.
Come to think of it, the last three movies I watched all the way through had strong female leads. She Kills (2016) was painful to watch, but I was intrigued by Jennie Russo. Firelight (1997) was a visual treat, with a stunning performance by Sophie Marceau.
I've given up on TV series and can’t remember the last one I watched.
