I regularly go to a nearby cinema that also shows older movies. Watching a movie like "Ran" (Akira Kurosawa) in a restored 4k version on a big screen is quite an experience. (Tickets are 10€ btw.) Often I go with a friend, but occasionally I also go alone. There's something about spending 2 or 3 hours in a dark room entirely focussing on a piece of art.
