I think it’s more like admitting that some of the movies you’ve seen were boring and disappointing but, rather than declaring all movies must be boring and disappointing, you now hone in on which genres or directors or writers or actors have been more enjoyable to watch. It’s a refinement process where you focus on which movies bring you satisfaction or contentment or at least amusement, regardless of whether other people say they are good movies or not. Then you watch more of the movies and stop wasting energy on the ones you know don’t work for you.
