moviegoer
A person who regularly goes to movie theaters to watch films.
A moviegoer is someone who goes to see movies at a theater regularly or frequently. Unlike someone who only watches movies at home or catches an occasional blockbuster, a moviegoer makes seeing films on the big screen a real habit.
The word captures something about routine and enthusiasm. Your aunt who sees a new movie every weekend is a dedicated moviegoer. Someone who only streams movies at home wouldn't be called one, even if they watch dozens of films. The term specifically means going out to theaters, buying tickets, settling into those seats, and experiencing movies on the big screen surrounded by other people reacting to the same story.
Theaters often design their schedules and offerings with moviegoers in mind, knowing these regulars will show up for everything from summer blockbusters to quiet independent films. Some moviegoers love the ritual: the previews, the popcorn, the darkness of the theater.
