As a filmmaker it's important to think critically as you watch other movies and TV shows. Really take the time to examine what you see on screen. Don't let the visuals was over you. Consider why directors make certain choices, and think about how these choices convey information about story and character. One of the things to look for is how a director shoots a dialogue scene, Shot/Reverse shot is a trait common among every film or TV show and yet the audience can still learn a lot about tone, themes, story, and character just by observing the composition of these shots.
