When I am not making the preverbial "view the plane from seat" drawings I love to watch movies that are playing on other people's headrests.
It gives me the opportunity to concentrate purely on the visuals. How does the editor pace the various scenes. How does the director or DP frame shots? How does the colorist set the visual tones for scenes? How well do the actors portray their emotions.
Give it a try if you haven't. It is a fun exercise.
