I have stopped watch live TV like 12 years ago (at least, not sure exactly), that was the first step, but still watching movies and series. No I realize I watch lesd than one movie a month and maybe 4-5 TV show episodes, when I'm in the mood for something specific. Like you, on lunch break or in the train when travelling.
Most of the time I'm feeling like I will watch something, I have a long list of more important, more interesting, thing to do first, so I didn't and postpone the movie.
