Depends on the movie. I like to watch them for movies I know I will never see and have no desire to see, and more focus on non-mainstream or foreign films. I prefer other mediums to movies so I probably watch fewer than 20 movies a year.

For example, I watched one about a Japanese movie where cockroach humanoids now inhabit Mars and they have to send humans with the ability to transform into other bugs to retrieve some data. An absolutely outrageous movie that I would otherwise never know existed and would never see willingly. So instead I watched a twenty minute summary of the movie while doing something else
